Mark Kirk
Mark Steven Kirk (born September 15, 1959) is an American retired politician, attorney, and former naval intelligence officer who represented Illinois in the United States Senate from 2011 to 2017 as a Republican.[1] Prior to his Senate service, Kirk held Illinois's 10th congressional district seat in the U.S. House of Representatives for five terms from 2001 to 2011.[2] He entered public service after graduating from Cornell University and Georgetown University Law Center, working as a congressional staffer, at the U.S. State Department, and in private law practice, while concurrently serving 23 years in the U.S. Navy Reserve, attaining the rank of commander before retiring in 2013.[3][4] Kirk's congressional career emphasized fiscal conservatism and national security, including roles on appropriations subcommittees overseeing military construction and veterans affairs.[5] As a self-described moderate Republican in a politically divided state, he collaborated across party lines on issues such as financial regulation and foreign policy, though his voting record aligned with Republican positions approximately 74% of the time.[6] In 2012, Kirk experienced a severe stroke that resulted in partial paralysis on his left side and required extensive rehabilitation, impacting his legislative productivity and contributing to his narrow defeat in the 2016 Senate election by Democrat Tammy Duckworth.[7][8] Post-Congress, Kirk has engaged in international policy advisory roles, leveraging his military and legislative experience.[9]Background
Early Life and Education
Mark Steven Kirk was born on September 15, 1959, in Champaign, Champaign County, Illinois.[10][1] He grew up in the Chicago suburbs and graduated from New Trier High School in Winnetka, Illinois.[3] Kirk subsequently attended Blackburn College and the Universidad Nacional Autónoma de México in Mexico City.[3][8] Kirk earned a Bachelor of Arts degree in history cum laude from Cornell University in 1981.[10][8] During his time at Cornell, he worked at a nursery school.[11] He then obtained a Master of Science degree in economics from the London School of Economics in 1982.[8][3] Following his master's, Kirk taught for one year at a private school in London.[11] He completed his formal education with a Juris Doctor from Georgetown University Law Center.[3][8]Pre-Political Career
Early Professional Roles
Following his master's degree from the London School of Economics in 1982, Kirk began his professional career in congressional staff work, serving as a legislative assistant and advancing to chief of staff for U.S. Representative John Porter (R-IL) from 1984 to 1990.[12][1][13] In this role, he handled legislative matters for Porter, who represented Illinois's 10th congressional district, which Kirk would later contest. From 1990 to 1991, Kirk worked as an officer at the World Bank's International Finance Corporation, focusing on international financial operations.[13] Kirk then joined the U.S. Department of State as a special assistant to the Assistant Secretary for Western Hemisphere Affairs from 1992 to 1993, contributing to policy on Central American issues amid ongoing peace processes.[12][1] After obtaining his J.D. from Georgetown University Law Center in 1992, Kirk practiced international law at the firm Baker & McKenzie from 1993 to 1995.[3] In 1995, he returned to Capitol Hill as counsel to the House International Relations Committee, where he advised on foreign policy matters until 1999, prior to his successful 2000 campaign for the U.S. House.[1][3]Military Service
Mark Kirk was commissioned as an ensign in the United States Naval Reserve in 1989 and served as an intelligence officer for 23 years, retiring with the rank of commander on December 15, 2014.[14][4] During his tenure, Kirk held roles with the Defense Intelligence Agency in the National Military Joint Intelligence Center at the Pentagon, where he monitored global military activities and oversaw the intelligence section of the alert center during active duty shifts.[5][15] He participated in deployments including service in Panama as an intelligence officer and a 1999 tour with a Navy Reserve EA-6B squadron during Operation Allied Force, during which he organized the squadron's intelligence operations from April to June.[16][17] Kirk's reserve duties also involved supporting counterterrorism efforts, with tours in Bahrain aligned with Operations Enduring Freedom and Iraqi Freedom, though his service was primarily in intelligence analysis rather than combat zones.[14]Congressional Career
U.S. House of Representatives
Mark Kirk was elected to represent Illinois's 10th congressional district in the U.S. House of Representatives on November 7, 2000, defeating one-term Democratic incumbent Lauren Beth Gash by 2,151 votes in a competitive race covering affluent northern Chicago suburbs including [North Shore](/page/North Shore) communities like Evanston, Wilmette, and Lake Forest.[18] He assumed office on January 3, 2001, as a Republican emphasizing fiscal restraint and national security, drawing on his prior experience as a staffer for the House International Relations Committee.[1] During his tenure, Kirk focused on appropriations matters, serving on the House Appropriations Committee and its subcommittees on Commerce, Justice, Science, and Related Agencies, as well as State, Foreign Operations, and Related Programs, where he influenced funding for foreign aid and domestic science initiatives.[2] Kirk secured re-election in 2002 with 58% of the vote against Democrat Lee Goodman, in 2004 with 64% against Kurt Klein, in 2006 with 53% against Dan Seals amid a Democratic wave year, and in 2008 with a narrow 51%-49% margin over Seals in one of the closest House races that cycle.[19][20] The district's moderate electorate, blending suburban conservatives with independents and some Democratic-leaning areas, rewarded his centrist approach, including support for earmark transparency reforms and opposition to unchecked federal spending.[21] He co-sponsored legislation to provide marriage penalty relief in tax codes during the 107th Congress, aiming to reduce burdens on dual-income households.[22] As a self-described fiscal hawk, Kirk voted for the 2001 and 2003 Bush tax cuts but criticized excessive earmarks, pushing for greater accountability in appropriations processes.[3] His record reflected independence from strict party lines, earning low scores from conservative groups like Heritage Action for deviations on issues such as environmental protections for the Great Lakes, which he championed through bills to prevent invasive species and pollution affecting over 30 million regional residents.[23][21] Kirk resigned from the House on November 29, 2010, after winning election to the U.S. Senate, having served five terms without major ethical scandals during his House career.[1]U.S. Senate
Mark Kirk was elected to the United States Senate from Illinois on November 2, 2010, defeating Democratic state Treasurer Alexi Giannoulias by a margin of 54.8% to 40.1%.[24] The victory marked a significant upset in the Democratic-leaning state, securing the seat previously held by Barack Obama. Kirk was sworn into office on November 29, 2010, to complete the remainder of Obama's term ending January 3, 2011, and then served the full six-year term from January 3, 2011, to January 3, 2017.[10] During his Senate tenure, Kirk held assignments on the Appropriations Committee, including subcommittees on Financial Services and General Government, Military Construction and Veterans Affairs, and Transportation, Housing and Urban Development, and Related Agencies; the Banking, Housing, and Urban Affairs Committee; and the Committee on the Environment and Public Works.[25] He focused on fiscal restraint, military funding, and infrastructure initiatives, often positioning himself as a moderate Republican willing to cross party lines on select issues.[3] On January 21, 2012, Kirk suffered a massive stroke while in his Chicago office, leading to three brain surgeries and months of intensive rehabilitation at the Rehabilitation Institute of Chicago.[26] He returned to the Senate on January 3, 2013, after nearly a year of absence, demonstrating physical progress by climbing the Capitol steps unaided. His neurosurgeon later confirmed a full cognitive recovery, though physical limitations from the stroke persisted.[27][28] Kirk sought re-election in 2016 but lost to Democratic U.S. Representative Tammy Duckworth, garnering 38.8% of the vote to Duckworth's 56.8% in a race marked by debates over his health and policy differences.[29] The defeat ended his congressional career after 16 years, with Kirk conceding on November 8, 2016.[30]Policy Positions
Foreign Policy
Kirk was a leading advocate for stringent economic sanctions against Iran to curb its nuclear program and regional influence. In December 2011, he co-sponsored an amendment to the National Defense Authorization Act imposing sanctions on Iran's central bank and energy sector, which passed the Senate 100-0.[31] In January 2015, Kirk and Senator Robert Menendez introduced the Nuclear Weapon Free Iran Act, which sought to impose additional penalties unless Iran verifiably dismantled its nuclear weapons capabilities, ballistic missile program, and support for terrorism; the bill garnered 16 co-sponsors but faced opposition from the Obama administration.[32] He criticized the 2015 Joint Comprehensive Plan of Action as akin to appeasement of Nazi Germany, arguing it would accelerate Iran's path to nuclear weapons and compel Israel to act unilaterally.[33] On Israel, Kirk prioritized bolstering its defense capabilities amid threats from Iran and its proxies. He lobbied the Pentagon to provide Israel with direct access to U.S. satellite feeds for real-time detection of Iranian missile launches, enhancing Israel's early warning systems.[34] In 2016, the Simon Wiesenthal Center awarded him its Distinguished Public Service Award for advancing Israel's security, combating global terrorism, and opposing a nuclear-armed Iran.[35] Kirk associated with groups like United Against Nuclear Iran, using his Senate platform to build coalitions for policies isolating Tehran.[5] Regarding Russia and Ukraine, Kirk pushed for robust U.S. support to counter Russian aggression following the 2014 annexation of Crimea. He co-sponsored the Ukraine Freedom Support Act of 2014, authorizing lethal aid including anti-tank weapons and sanctions on Russian entities in the arms sector.[36] In March 2014, he called for authorizing sanctions on Russian officials and providing offensive weaponry to Ukrainian forces to deter further incursions.[37] [38] In Asia, Kirk emphasized engagement with China while addressing security concerns. He founded and co-chaired the bipartisan U.S.-China Working Group in both the House and Senate to foster trade, dialogue, and mutual understanding, conducting multiple trips to Beijing.[6] In 2011, alongside Senator Charles Schumer, he accused China of evading U.S. sanctions on Iran by importing Iranian oil, urging stricter enforcement.[39] Kirk voted against measures deterring foreign arms sales to China but supported cooperation with India as a nuclear power and aid for democratic institutions in Pakistan.[40]Economic and Fiscal Policy
During his tenure in the U.S. House of Representatives from 2001 to 2010 and the Senate from 2011 to 2017, Mark Kirk generally advocated for tax reductions and fiscal restraint, though his record reflected pragmatic deviations from strict conservatism, as evidenced by a lifetime Heritage Action score of 38%, below the average for Senate Republicans.[23] He supported the Economic Growth and Tax Relief Reconciliation Act of 2001 and the Jobs and Growth Tax Relief Reconciliation Act of 2003, voting in April 2002 to make the Bush-era tax cuts permanent, which reduced marginal income tax rates across brackets and expanded child tax credits.[40] Kirk also backed eliminating the federal estate tax, voting yes on repeal measures in April 2001, and endorsed simplifying the tax code while ending the marriage penalty.[40] He opposed tax hikes, stating in December 2009 that "a tax increase is the surest way to turn recession into depression."[40] On budget and debt issues, Kirk prioritized reducing federal deficits, pledging in September 2000 to "pay down the national debt" and cut wasteful spending.[40] In January 2012, he expressed disapproval of raising the debt limit, aligning with efforts to impose spending discipline.[40] Kirk criticized excessive government intervention, opposing a federal bailout for Illinois' fiscal woes in October 2010 and advocating an early termination of the Troubled Asset Relief Program (TARP) to limit its scope beyond initial bank stabilizations.[41][40] Kirk's responses to economic crises showed selectivity on stimulus measures. He voted against the $787 billion American Recovery and Reinvestment Act of 2009, the Obama administration's signature stimulus package, and opposed a $15 billion bailout for General Motors and Chrysler in December 2008.[40] However, he supported a smaller $192 billion additional anti-recession spending bill in July 2009 and later called for bipartisan oversight of stimulus funds to ensure accountability.[40] In the Senate, he voted for continuing appropriations in 2015 and 2016 to fund government operations, reflecting compromises to avoid shutdowns amid broader fiscal debates.[42] Kirk favored pro-growth policies for jobs and trade, proposing a "Small Business Bill of Rights" with a 10-point agenda in October 2010 and supporting free trade pacts, such as the U.S.-Peru agreement in November 2007, to expand export opportunities.[40] He voted to raise the federal minimum wage to $7.25 per hour in January 2007, prioritizing employment incentives over rigid wage controls.[40] These positions underscored a blend of market-oriented reforms with targeted interventions, often diverging from party orthodoxy on spending amid Illinois' economic challenges.Infrastructure and Domestic Issues
Kirk introduced the Building and Renewing Infrastructure for Development and Growth in Employment (BRIDGE) Act in 2011, which aimed to facilitate private investment in public infrastructure projects by removing federal restrictions on public-private partnerships and providing states greater flexibility to generate transportation revenue, potentially unlocking up to $100 billion for such initiatives.[43][44] Alongside Senator Mark Warner, he co-sponsored bipartisan legislation directing the U.S. Department of Transportation to establish pilot programs enhancing standards and efficiency for transportation projects, including through innovative financing and performance-based evaluations.[45] In collaboration with Illinois Senator Dick Durbin, Kirk supported the Water Resources Reform and Development Act of 2014, which authorized Army Corps of Engineers projects prioritizing Illinois infrastructure needs such as port maintenance, harbor improvements, and flood control, passing both chambers and signed into law on June 10, 2014.[46] On waterway and regional infrastructure, Kirk advocated for enhanced funding to protect the Great Lakes from invasive species and upgrade Illinois waterways, voting in favor of the Water Infrastructure Improvements for the Nation Act on April 14, 2016, which allocated resources for lock and dam repairs and ecosystem restoration benefiting Midwest commerce and navigation.[47] His approach emphasized leveraging private sector involvement and bipartisan cooperation to address aging transportation networks, contrasting with more government-centric funding models. Regarding broader domestic energy and environmental policies, Kirk supported the Energy Policy Modernization Act of 2016 (S. 2012), which passed the Senate on April 28, 2016, promoting domestic energy production including natural gas exports, pipeline safety, and research into carbon capture technologies while modernizing federal leasing for oil and renewables.[23] He endorsed nuclear energy development, Yucca Mountain repository reopening, and new refinery construction to bolster energy independence, voting against EPA authority to regulate greenhouse gases via endangerment findings in 2010.[40] On climate change, Kirk stated in January 2015 that it constitutes a real phenomenon partly driven by human activity, though he opposed carbon taxes and later emphasized natural cycles like Greenland ice melt in critiquing emission-focused regulations; his record included votes both preserving (November 2015 against Clean Power Plan repeal) and challenging (October 2015 support for its dismantlement) Obama-era environmental rules, reflecting pragmatic rather than ideological consistency.[48][49][50]Social and Cultural Issues
Kirk held moderate to liberal positions on several social issues, diverging from many in his party. On abortion, he supported a woman's right to choose and opposed restrictive federal measures. In September 2015, Kirk was one of only two Republicans to vote against a bill banning abortions after 20 weeks of gestation, citing concerns over exceptions for rape, incest, and maternal health.[51] He also advocated funding Planned Parenthood for non-abortion health services, such as cancer screenings and family planning, while earning a 100% rating from NARAL Pro-Choice America for his pro-choice voting record in the House.[40] Regarding embryonic stem cell research, Kirk consistently backed expansion of federal funding. In 2005, as a House member, he co-sponsored legislation to overturn President George W. Bush's restrictions on using new embryonic stem cell lines for research, arguing it advanced scientific progress without creating new embryos.[52] He voted yes on Senate bills in 2007 and 2005 to broaden research access, positioning himself against conservative opposition rooted in ethical concerns over embryo destruction.[40] On LGBT rights, Kirk emerged as an early Republican supporter of same-sex marriage. In April 2013, he publicly endorsed marriage equality, stating that legally discriminating against same-sex couples was "an anathema" and emphasizing personal freedom in defining love, influenced partly by his recovery from a stroke and interactions with LGBT constituents.[53][54] This made him the second sitting GOP senator to do so, following Rob Portman. He voted against a 2004 constitutional amendment banning same-sex marriage and co-sponsored the Equality Act to prohibit discrimination based on sexual orientation and gender identity.[40][55] The Human Rights Campaign rated him 75% on gay rights issues and endorsed his 2016 re-election for leadership on bullying prevention and equality efforts.[56] Kirk favored enhanced gun control measures, particularly after mass shootings. Following the 2012 Aurora theater shooting in his state, he supported universal background checks and restrictions on high-capacity magazines.[40] In June 2016, after the Orlando nightclub attack, he voted for four bills expanding background checks, denying firearms to suspected terrorists, and closing loopholes, breaking from most Republicans.[57][58] These positions earned him an "F" rating from the NRA and endorsement from gun control advocate Gabby Giffords, though he lost support from some pro-gun groups.[59] On family values and religion, Kirk's record aligned moderately with conservative priorities in some areas. He voted to protect the Pledge of Allegiance's reference to "under God" in 2004 and received a 69% rating from the Christian Coalition for pro-family stances.[40] However, his overall social liberalism drew criticism from social conservatives, contributing to primary challenges.Controversies
Military Service Claims
In 2010, during his U.S. Senate campaign, Mark Kirk faced scrutiny for multiple inaccuracies regarding his Navy Reserve service, prompting him to issue apologies and commit to correcting his record. He had claimed to be the only member of Congress to serve in Operation Iraqi Freedom, but his duties were stateside and did not involve deployment to the theater of operations.[60] Similarly, Kirk stated he commanded the war room in the Pentagon, an assertion later deemed an exaggeration of his intelligence planning role.[60] He also misrepresented receiving the U.S. Navy's Intelligence Officer of the Year award personally, whereas it was a unit commendation shared by his squadron.[61] [60] Further discrepancies included claiming participation as a veteran of Operation Desert Storm, which records show he did not undertake, and asserting that his airplane came under fire during intelligence missions over Iraq in 2000, for which no supporting documentation exists.[61] Kirk attributed these errors to carelessness rather than intent, apologizing publicly and pledging to release his fitness reports while vowing to understate his achievements moving forward; his campaign updated resumes and bios accordingly after media inquiries from outlets including The Washington Post.[61] Despite the misstatements, Kirk's 23-year Reserve career involved legitimate contributions, such as target selection for Tomahawk missiles during the 1991 Gulf War from Washington, D.C., and support for the 1999 Kosovo air campaign via electronic warfare planning.[4] [15] The issue resurfaced in September 2016 when Kirk's reelection campaign website described him as a "veteran of the Iraq war" on a veterans' issues page, despite his service remaining domestic during that conflict with no combat deployment.[62] The campaign blamed a third-party vendor for the unvetted error, promptly restricting the page after CNN's inquiry, but critics linked it to the 2010 pattern of embellishment.[62] Kirk, who retired from the Navy Reserve in December 2014 as a commander, did not issue a direct apology for the 2016 claim but had previously emphasized his intelligence roles in global operations without overseas combat exposure.[4]Campaign Statements and Political Breaks
During his 2016 re-election campaign against Democratic challenger Tammy Duckworth, Kirk refused to endorse Donald Trump for president, stating on June 16 that Trump was "too bigoted and racist" for Illinois voters due to his comments on a federal judge of Mexican heritage.[63] This marked an early public break with the emerging Republican presidential nominee, following Kirk's initial retraction of support on June 7 after Trump's remarks on Judge Gonzalo Curiel, which Kirk deemed "un-American."[64] Kirk's stance aligned with his moderate positioning in a Democratic-leaning state but drew criticism from party conservatives, contributing to perceptions of him as a "RINO" (Republican In Name Only).[65] In April 2016, amid his Senate campaign, Kirk broke from most Republican senators by advocating for Senate votes on Democratic Supreme Court nominee Merrick Garland, arguing it would allow public scrutiny rather than outright rejection, a position that further highlighted his willingness to diverge from GOP leadership on judicial nominations.[65] This deviation, uncommon among Senate Republicans at the time, underscored Kirk's emphasis on process over partisan blockade but alienated some base voters in his competitive race. Kirk's campaign also featured verbal gaffes that amplified scrutiny. On June 11, 2015—early in his re-election preparations—a hot microphone captured him referring to unmarried Republican colleague Lindsey Graham as a "bro with no ho," a crude remark implying lack of a romantic partner, which he later dismissed as joking but which complicated his image as a statesman.[66] More damagingly, during an October 27, 2016, debate with Duckworth, Kirk sarcastically remarked, "I had forgotten that your parents came all the way from Thailand to serve George Washington," questioning her heritage and family's purported Revolutionary War ties in a racially tinged attack on her military service narrative.[67] He apologized the next day, calling it an "off-the-cuff" error, but the incident prompted the Human Rights Campaign to revoke its endorsement on October 29 and fueled Democratic attacks portraying him as erratic.[68][69] These statements, amid a tightening race, were cited by observers as self-inflicted wounds that eroded Kirk's viability, leading to his loss by nearly 15 points on November 8, 2016.[70]Post-Congressional Activities
Private Sector and Advocacy
Following his defeat in the 2016 U.S. Senate election and departure from office in January 2017, Mark Kirk founded Kirk Global Advisors, a strategic advisory firm specializing in guidance at the intersection of business, politics, national security, and international trade.[8][71] The firm provides consulting services to clients navigating geopolitical risks and policy environments, drawing on Kirk's prior experience in foreign affairs and finance.[72] Kirk registered as a lobbyist in May 2019, initially as a subcontractor to BGR Group representing the China-United States Exchange Foundation, a Hong Kong-based nonprofit affiliated with pro-Beijing interests, on issues including U.S.-China relations and trade policy.[73] In the same year, through Kirk Global Advisors, he lobbied for one client on unspecified matters, with disclosures indicating activity under the Lobbying Disclosure Act.[74] By September 2019, Kirk served as executive partner for U.S. Blockchain Advocacy Partners, advocating for blockchain technology policies until 2021.[8] In September 2020, he and associate Ronna King retroactively registered as lobbyists for work conducted since 2019 via Kirk Global Advisors, covering contacts with U.S. government officials on behalf of private clients.[75] In advocacy, Kirk joined the Board of Advisors of United Against Nuclear Iran (UANI) in June 2017, contributing expertise on sanctions and Iran policy based on his Senate record of sponsoring legislation like the Iran Sanctions Act amendments.[76] He has remained on the Board of Directors of the International Republican Institute (IRI), a democracy-promotion nonprofit, a role he assumed in 2012 and continued post-Congress to support international election monitoring and governance initiatives in over 100 countries.[9] These positions align with Kirk's longstanding focus on human rights and countering authoritarian regimes, though his advisory work has included engagements with entities linked to foreign governments, prompting scrutiny over potential conflicts in disclosure filings.[77]Personal Life
Family and Relationships
Mark Steven Kirk was born on September 15, 1959, in Champaign, Illinois, to Francis Gabriel Kirk and Judith Ann Brady Kirk.[78] His mother, Judith Brady Kirk, died on August 10, 2020, at the age of 84 in Evanston, Illinois.[79] In August 2001, Kirk married Kimberly Ann Vertolli, an attorney based in the Washington, D.C., area; the couple divorced in June 2009 after eight years of marriage.[8] [80] Kirk and Vertolli had no children.[8] No public records indicate Kirk has remarried or entered into subsequent long-term relationships as of 2025.[21]Health Challenges and Recovery
On January 21, 2012, U.S. Senator Mark Kirk suffered an ischemic stroke in his Washington, D.C., office, triggered by a tear in his right carotid artery that led to dizziness and subsequent hospitalization.[81] Doctors performed emergency surgery to reduce brain swelling, but the event resulted in significant physical impairment, including partial paralysis on the left side of his body.[7][82] Kirk underwent intensive rehabilitation at the Rehabilitation Institute of Chicago, focusing on relearning basic motor functions such as walking hallways, climbing stairs, and entering vehicles.[83] He was discharged from the facility on May 3, 2012, after approximately three months, transitioning to outpatient therapy that included logging over 10 miles of walking practice.[84][85] By late 2012, he resumed Senate duties on January 3, 2013, symbolically ascending the 45 steps of the U.S. Capitol unaided to demonstrate progress, though he relied on experimental high-intensity therapies to regain mobility.[86][87] Despite cognitive functions remaining intact—confirmed by his neurosurgeon as a "full cognitive recovery" in a 2016 letter—Kirk faced persistent physical limitations, including no functional use of his left arm and hand, restricted left leg mobility, and frequent wheelchair dependence for longer distances.[88][28][89] In 2014, he described the recovery as ongoing and patient-oriented, emphasizing neuroplasticity-driven exercises to mitigate long-term deficits.[90] These challenges contributed to scrutiny during his 2016 reelection campaign, though he continued legislative work with accommodations.[89]Electoral History
Kirk first won election to the U.S. House of Representatives in the 2000 election for Illinois's 10th congressional district, defeating Democratic state representative Lauren Beth Gash.[91] He secured reelection in 2002, 2004, 2006, and 2008, with margins narrowing in the latter two cycles against Democratic challenger Dan Seals amid a shifting suburban electorate.[1] In 2010, Kirk won election to the U.S. Senate, capturing the seat previously held by Barack Obama by defeating Democratic state treasurer Alexi Giannoulias. Kirk received 1,778,698 votes (54.3 percent), while Giannoulias garnered 1,306,284 votes (39.8 percent); independent candidates accounted for the remainder.[92]| Election Year | Office | Party | Votes | Percentage | Opponent (Party) | Votes | Percentage | Result |
