John Cornyn III is an American politician, attorney, and former jurist serving as the senior United States senator for Texas, a seat he has held since 2002. He is a member of the Republican Party.
Born in Houston, Cornyn is a graduate of Trinity University and St. Mary's University School of Law and received an LL.M. degree from the University of Virginia School of Law. He was a judge on Texas's 37th District Court from 1985 to 1991, an associate justice of the Texas Supreme Court from 1991 to 1997, and Attorney General of Texas from 1999 to 2002. He was first elected to the U.S. Senate in 2002, and was reelected in 2008, 2014, and 2020. During his tenure, Cornyn chaired the National Republican Senatorial Committee from 2009 to 2013 and served as the Senate Republican whip from 2013 to 2019.
Often regarded as an institutional or moderate Republican, Cornyn has frequently played a role as a deal-maker and within the Senate. After the 2020 presidential election, he declined to join efforts by Republican lawmakers to challenge the certification of the election results and publicly criticized a Texas-led lawsuit seeking to overturn the outcome in several states. In 2022, Cornyn was the lead Republican negotiator for the Bipartisan Safer Communities Act, the most significant federal gun control legislation in decades. He has also supported bipartisan legislation reforming the Electoral Count Act and has said Congress should consider legislation addressing the legal status of DACA recipients as part of broader immigration discussions. Cornyn's votes and positions have drawn criticism from conservative activists and primary challengers in his 2026 re-election campaign. If reelected, Cornyn is set to become the dean of Texas's congressional delegation.

Texas attorney general
1998 election
In 1998, Cornyn ran for Texas attorney general. In the March Republican primary, Railroad Commissioner Barry Williamson received 38% of the vote, and Cornyn, a former Texas Supreme Court justice, received 32%. In the April runoff election, Cornyn defeated Williamson, 58% to 42%. Cornyn won the general election with 54% of the vote; he defeated Jim Mattox, a former Texas attorney general and U.S. representative. Cornyn was the first Republican-elected attorney general of Texas since Reconstruction, and was sworn in by then-Governor George W. Bush.Tenure
In September 2000, Cornyn created the Texas Internet Bureau to investigate illegal internet practices. The Internet Bureau was funded through an $800,000 grant from Governor Bush’s office, and its mission was to "help fight cybercrime in Texas, including consumer fraud, hacker break-ins, and online child exploitation". Cornyn investigated fraudulent Medicare and Medicaid claims.Cornyn was criticized by civil rights groups for failing to investigate in a timely manner the false drug convictions of numerous African Americans in Tulia, Texas. On September 6, 2002, The Austin Chronicle reported that Cornyn had announced that his office would investigate the 1999 drug bust, where the testimony of one narcotics agent led to the arrests of 46 people, 43 of whom were Black.
In 2005, Cornyn was mentioned as a possible replacement for Supreme Court Justices Sandra Day O'Connor and William Rehnquist.
United States Senate
Elections
2002
In the 2002 Republican primary, Cornyn faced five opponents. Cornyn defeated his closest Republican challenger, the self-financed, Dallas-based international physician Bruce Rusty Lang, by a ten-to-one margin. In the general election, Cornyn defeated Democratic nominee Ron Kirk in a campaign that cost each candidate over $9 million.2008
had not elected a Democrat in a statewide election since 1994, and according to Rasmussen Reports polling, Cornyn had an approval rating of 50% in October 2008. Christian activist Larry Kilgore of Mansfield challenged Cornyn in the Republican primary, but Cornyn easily defeated him. Texas Representative Rick Noriega won the March4 Democratic primary against Gene Kelly, Ray McMurrey, and Rhett Smith. Yvonne Adams Schick was the Libertarian Party's nominee, and the Green Party of Texas sought ballot access for its candidate, David B. Collins. The same Rasmussen poll showed Cornyn leading Noriega 47% to 43%, suggesting that the race might prove unexpectedly competitive, but most polls showed a much wider margin, and Cornyn was reelected.2014
Cornyn was reelected in 2014, and according to the Dallas Morning News, "never broke a sweat." He won the March Republican primary with 59% of the vote against Houston-area congressman Steve Stockman. In the general election, he raised $14 million, outspending Democratic nominee David Alameel by nearly 3-1. Cornyn won again by over 20 points.2020
Cornyn was reelected to a fourth term in 2020 in the closest of his Senate campaigns. He won the primary with 76% of the vote, and then defeated Democrat MJ Hegar in a race that the Cook Political Report had initially rated "Likely Republican" but then shifted to "Lean Republican". Cornyn received 5,962,983 votes—more than any Republican Senate candidate had ever received before, breaking the record set by Pete Wilson of California in 1988. Hegar also set a record, getting more votes than any losing Democrat since Leo T. McCarthy in the 1988 California Senate race.2026
Cornyn has announced his candidacy for a fifth Senate term in 2026. He faces Texas Attorney General Ken Paxton in the primary.Tenure
In 2004, Cornyn co-founded and became the co-chairman of the U.S. Senate India Caucus. In December 2006, he was selected by his colleagues to join the five-person Republican Senate leadership team as Vice Chairman of the Senate Republican Conference.In 2005, Cornyn gained notice by connecting the Supreme Court's reluctance to hear arguments for sustaining Terri Schiavo's life with the recent murders of Judge Joan Lefkow's husband and mother, as well as the courtroom murder of Judge Rowland Barnes. Cornyn said: "I don't know if there is a cause-and-effect connection, but we have seen some recent episodes of courthouse violence in this country. I wonder whether there may be some connection between the perception in some quarters on some occasions, where judges are making political decisions, yet are unaccountable to the public, that it builds up and builds up, and building up to the point where some people engage in violence." His statement and a similar one by House Majority Leader Tom DeLay were widely denounced, including by The New York Times. Cornyn later said that the statement was taken out of context, and for that reason, he regretted the statement.
On May 18, 2007, Cornyn was involved in a verbal altercation with Senator John McCain. During a meeting on immigration, McCain and Cornyn had a shouting match when Cornyn started questioning the number of judicial appeals that illegal immigrants could receive. McCain responded by yelling profanity and insults at Cornyn, and followed up with the assertion, "I know more about this than anyone else in the room." Previously, Cornyn told McCain: "Wait a second here. I've been sitting in here for all of these negotiations, and you just parachute in here on the last day. You're out of line."
As chairman of the National Republican Senatorial Committee, Cornyn was a strong supporter of Norm Coleman's various court challenges to the 2008 election certification of the Minnesota U.S. Senate race. Cornyn advocated for Coleman to bring the case before the federal court and said the trial and appeals could take years to complete. Cornyn threatened that Republicans would wage a "World War III" if Senate Democrats had attempted to seat Democratic candidate Al Franken before the appeals were complete. Coleman conceded after the Minnesota Supreme Court unanimously ruled that Franken had won the election.
Cornyn voted to confirm Samuel Alito as an Associate Justice of the Supreme Court and John Roberts as Chief Justice. In September 2005, during Roberts's Supreme Court hearings, Cornyn's staff passed out bingo cards to reporters. He asked them to stamp their card every time a Democrat on the Judiciary Committee used terms such as "far right" or "extremist". On July 24, 2009, Cornyn announced his intention to vote against President Obama's Supreme Court nominee Sonia Sotomayor, saying that she might rule "from a liberal, activist perspective".
On the day of Obama's inauguration, it was reported that Cornyn would prevent Hillary Clinton from being confirmed as secretary of state by unanimous floor vote that day. Senate Majority Leader Harry Reid's spokesman reported to the Associated Press that a roll call vote for the Clinton confirmation would be held instead on the following day, January 21, 2009, and that it was expected Clinton would "receive overwhelming bipartisan support". The vote was 94–2 in her favor, with only Senators Jim DeMint and David Vitter voting in opposition.
On March 18, 2020, Cornyn blamed the COVID-19 pandemic on cultural practices in China and mistakenly blamed China for the MERS and swine flu epidemics. His comments were criticized by some Democrats and the National Council of Asian Americans and Pacific Islanders. At the time, the consensus among researchers was that coronavirus had originated at a wet market in Wuhan, China.
