John Cornyn is a four-term U.S. Senator from Texas who has served since 2002. Born in Houston, he previously served as Texas Attorney General (1999-2002) and on the Texas Supreme Court (1991-1997). He was the Senate Republican Whip from 2013 to 2019 and narrowly lost a bid for Senate Majority Leader in 2024. Cornyn has positioned himself as a conservative with a record of bipartisan dealmaking, though this has drawn criticism from the GOP's right wing who view him as insufficiently conservative and insufficiently loyal to President Trump.
John Cornyn was born in Houston to a U.S. Air Force colonel. He attended schools including the American School in Japan and graduated from Trinity University, St. Mary's University School of Law, and earned an LLM from University of Virginia. Before his Senate career, he served as a Texas District Court judge (1985-1991), Texas Supreme Court justice (1991-1997), and Texas Attorney General (1999-2002). He has been married nearly 50 years and is a Texas Republican fixture who rose to Senate GOP leadership.
Supported bipartisan gun safety bill
Cornyn was instrumental in shepherding the first gun safety bill in a generation through the Senate after the Uvalde school shooting in 2022, a move that drew fierce backlash from conservative primary voters and Trump supporters who opposed any gun restrictions
Voting History: Voted YES on the bipartisan gun safety bill in 2022
Conditionally supported but tied to border policy
While Cornyn has historically supported Ukraine aid and co-sponsored the Ukraine Democracy Defense Lend-Lease Act, he voted against a 2023 bill to supply Ukraine, Israel and Taiwan with defense aid unless it included border and immigration policy overhauls, arguing border security is also a national security priority
Voting History: Voted NO on Ukraine aid without border provisions (December 2023)
Claims strong support but periodically broken with Trump
Cornyn has voted with Trump 92% of the time and voted to acquit Trump in both impeachment trials. However, he criticized Trump's actions on January 6 as 'reckless,' was skeptical of Trump's electability before 2024, opposed Trump's tariffs, and backed the bipartisan gun safety bill which Trump criticized. Trump has called him a 'RINO' on social media
Voting History: Multiple points of disagreement with Trump despite overall alignment
Conservative, pro-business tax cuts
Strong supporter of the 2017 Tax Cuts and Jobs Act which he helped pass as Senate Whip
Voting History: Voted YES on 2017 Tax Cuts and Jobs Act
Cornyn has a strongly conservative voting record with 24 years in the Senate. He has been a reliable Republican vote on most issues, though he has occasionally broken with the conservative base on bipartisan initiatives. His voting record shows 92% alignment with Trump's positions despite periodic public disagreements with the president.
