U.S. Senate
Elections 2010 Coons ran in the
2010 special election for the
U.S. Senate seat then held by Democrat Ted Kaufman, who was appointed after Joe Biden resigned to take office as vice president. Kaufman had been appointed as a placeholder, and did not run in the special election. Coons was unopposed in the Democratic primary, and expected to face Republican Congressman and former
Governor Mike Castle in the general election. Coons was considered a decided underdog due to Castle's moderate profile and longstanding popularity in the state, but the dynamics of the race significantly altered when
Christine O'Donnell, a
Tea Party Republican who had lost to Biden in 2008 and who was strongly opposed by the GOP establishment, upset Castle in the Republican primary. In the first post-primary polls,
Rasmussen Reports showed Coons with a double-digit lead over O'Donnell, describing this as a "remarkable turnaround" given that the race had leaned Republican before O'Donnell's primary victory. In the first week of October,
Fairleigh Dickinson University's PublicMind Poll showed Coons with a 17-point lead, 53%–36%, over O'Donnell, and that 85% of self-identified Democratic voters had united behind Coons, while only 68% of Republican voters endorsed O'Donnell. Days before the election, a second Fairleigh Dickinson poll showed Coons leading 57% to 36% among likely voters, and 72% to 20% among voters who described themselves as moderates. As polls closed at 8 p.m.
Eastern Standard Time, multiple news sources announced that Coons had defeated O'Donnell based on exit poll data. Final results gave Coons close to a 17-point margin over O'Donnell, with 56.6% of the vote to her 40%. During the campaign, Coons became embroiled in controversy over an article he wrote in 1985 for his college newspaper: "Chris Coons: The Making of a Bearded Marxist". In it, he described how, on a college trip to
Kenya, hearing wealthy Africans disparaging their country's
poor while studying under a "bright and eloquent Marxist professor" at the University of Nairobi helped transform him from a Republican to what
Fox News called a "Democrat suspicious of America's power and ideals". Coons campaign spokesman Dave Hoffman said the article's title was a humorous takeoff on a joke Coons's college friends had made about how his time outside the country had affected his outlook. "After witnessing crushing poverty and the consequences of the Reagan Administration's '
constructive engagement' with the
South African apartheid regime, he rethought his political views, returned to the America he loved and proudly registered as a Democrat", Hoffman said in a statement to
Politico. According to Fox News, Coons was "targeted by Republicans" over the 25-year-old piece, and then-
Senate-Majority-Leader Harry Reid's attempt to defend Coons by calling him "my pet" might have done more harm than good. Coons downplayed the article, as well as controversial past statements by O'Donnell, saying that voters were interested in current issues such as job creation and the national debt and not "statements that either of us made 20 or 30 years ago". O'Donnell also attracted significant controversy; she embellished her academic record on several occasions, and after comedian
Bill Maher aired a video clip of her admitting that she had "dabbled in witchcraft" while in high school, her campaign aired a widely mocked television ad that began with her saying "I am not a witch."
2014 Coons was elected to his first full term by defeating Republican challenger Kevin Wade and
Green Party candidate Andrew Groff on November 4, 2014. Wade, an engineer and businessman, also ran against U.S. Senator
Tom Carper in
2012. Coons won 55.8% of the popular vote (130,655 to Wade's 98,823 and to Groff's 4,560).
2020 In the 2020 Democratic primary election, Coons easily defeated technology executive Jessica Scarane, a progressive challenger endorsed by groups like
Brand New Congress. In the general election, Coons faced Republican nominee
Lauren Witzke, a controversial conservative activist and conspiracy theorist calling for a ten-year
immigration moratorium. Coons and Witzke took part in a digital debate hosted by the Jewish Federation of Delaware, in which they debated the merits of late
Supreme Court Justice Ruth Bader Ginsburg and the
Black Lives Matter movement, as well as Witzke's comments about the
QAnon conspiracy theory. In the November general election, Coons defeated Witzke, 59% to 38%.
Tenure 2010s On November 15, 2010, Coons was sworn in as Delaware's newest senator by Vice President Joe Biden, the former occupant of Coons's Senate seat.
Joe Manchin of
West Virginia was sworn in on the same day, though he took an advantage in seniority over Coons, as the former
governor of West Virginia. The
Affordable Care Act (commonly called Obamacare) had already been passed when Coons took office, but he has voted against repealing it, emphasizing that seniors in Delaware would have to pay higher prescription drug prices if it was repealed. In September 2017, Coons said the Graham-Cassidy bill, meant to replace the Affordable Care Act, would be playing "Russian roulette with the American health care system." On abortion, Coons has received a 100% rating from the
Planned Parenthood Action Fund and a 0% rating from the
National Right to Life Committee. In June 2013, after the death of Democratic senator
Frank Lautenberg of New Jersey, Coons was appointed to his seat on the influential Appropriations Committee, becoming the first senator from Delaware to serve on the committee in 40 years. As a result, he gave up his seat on the
Committee on Energy and Natural Resources. In October 2013, Coons announced the formation of the inaugural Senate Chicken Caucus in the United States Senate. He stated, "I hope that the Senate Chicken Caucus will give America's chicken producers a platform to better inform legislators about the industry's vital contributions to our economy, and promote policy solutions that help their businesses grow and thrive." On December 11, 2013, Coons introduced the
Victims of Child Abuse Act Reauthorization Act of 2013 (S. 1799; 113th Congress), a bill that would reauthorize the
Victims of Child Abuse Act of 1990 and would authorize funding through 2018 to help
child abuse victims. Coons said that "we have a responsibility to protect our children from violence and abuse." Obama described the Senate's vote against Adegbile as "a travesty based on wildly unfair character attacks against a good and qualified public servant." An open letter to Coons from students, faculty and alumni of the Yale Law and Divinity Schools, of which Coons is an alumnus, criticized his vote as "alarm[ing]" and "signal[ing] a lack of respect for the fundamental American legal principle that all parties have a right to zealous representation." Coons was mentioned as a possible replacement for the late
Justice Antonin Scalia in February 2016. In April 2017, after
President Trump tweeted that North Korea had "disrespected the wishes of China & its highly respected President" with a recent missile launch, Coons said Trump understood China was his sole "constructive path forward on North Korea" but that diplomacy would not work through tweeting. In July 2017, Coons voted in favor of the
Countering America's Adversaries Through Sanctions Act that placed
sanctions on Iran together with
Russia and
North Korea. In April 2018, following the FBI raid on the hotel room and offices of Trump's personal attorney,
Michael Cohen, Coons,
Cory Booker,
Lindsey Graham, and
Thom Tillis introduced new legislation to "limit President Trump's ability to fire special counsel
Robert Mueller". Termed the
Special Counsel Independence and Integrity Act, the legislation would allow any special counsel, in this case Mueller, to receive an "expedited judicial review" in the 10 days following being dismissed to determine whether the dismissal was appropriate. If not, the special counsel would be reinstated. At the same time, according to
The Hill, the bill would "codify regulations" that a special counsel could be fired only by a senior Justice Department official, while having to provide reasons in writing.
2020s In November 2020, Coons was named a candidate for
Secretary of State in the
Biden administration. Biden ultimately chose
Antony Blinken to lead the State Department, telling Coons, "I need you in the Senate." Coons was seen as among Biden's closest allies in the Senate, and co-chaired Biden's 2024 reelection campaign. , Israel, October 22, 2023 During the
2021 attack on the United States Capitol, Coons was evacuated from the Senate chambers, along with other senators and staff. He said there were "some scary and chaotic moments" during the attack. When the Senate reconvened to certify the
Electoral College vote count, Coons called for Trump's removal, saying he "poses a real and present threat to the future of our democracy". He called for the invocation of the
Twenty-Fifth Amendment to the United States Constitution the day after the event on
Good Morning America. That same day, January 7, he called for Republicans
Josh Hawley and
Ted Cruz, who both challenged the election results, to resign from the Senate.
Arctic Frost investigation In November 2025, following disclosures that the FBI's
Arctic Frost investigation had obtained phone records of Republican senators without notification, Coons expressed concern about the surveillance of legislators, saying, "On the surface of it, it would strike me as a significant invasion of the right of senators to conduct their jobs, so this is something that needs urgent follow-up." Coons also co-sponsored the Anti-Cash Grab Act, legislation introduced by Senators
Martin Heinrich and
Mark Kelly to repeal a provision in the government funding bill that allowed senators to sue for $500,000 in damages over seized phone records.
Conservative Shift on Third Circuit During Senator Coons' Tenure Senator Coons, then-Senator Carper, and President Biden declined to select a nominee for a judicial vacancy on the
Third Circuit in President Biden's home state of
Delaware even though the vacancy was announced in May 2024, more than eight months before President Biden's four-year term in office ended. The White House's and the Delaware U.S. Senate delegation's decision not to fill the
Third Circuit vacancy in President Biden's home state of Delaware, along with President Biden's unsuccessful nomination of
Adeel A. Mangi to another
Third Circuit vacancy, allowed President Trump to fill both seats in 2025 and flip the Third Circuit to a conservative majority. President Trump ultimately nominated
Jennifer Mascott, who had never taken the Delaware bar exam and was not licensed to practice law in Delaware, to the vacancy that Coons, Carper, and President Biden declined to fill in Biden's home state.
