Rep. Michael McCaul (R-TX), a former chairman of the House Foreign Affairs and Homeland Security Committees, announced Sunday that he will retire from Congress at the end of next year, after 11 terms in office.

McCaul, 63, has been a critical voice for traditional conservative internationalism at a time of rising isolationist sentiment among some factions of the GOP; he’s seen as a key leader who helped drive the passage of supplemental aid to Ukraine, Israel and Taiwan in the House last year.

The Texas congressman has been a staunch supporter of Israel and an Iran hawk in the House and has also been a lead Republican voice in support of expanded funding for the Nonprofit Security Grant Program, which helps protect Jewish and other vulnerable nonprofits.

“My father’s service in World War II inspired me to pursue a life of public service, with a focus on defending our great nation against global threats, and I have been proud to carry out that mission in Congress for more than two decades,” McCaul said in a statement. “I am ready for a new challenge in 2027 and look forward to continuing to serve my country in the national security and foreign policy realm.”

As the House Foreign Affairs Committee chairman, McCaul was seen as a bipartisan dealmaker who maintained good relationships with Democratic colleagues.

Prior to his time in Congress, McCaul was a career prosecutor — the chief of counterterrorism and national security for the U.S. attorney in the Western District of Texas, the deputy attorney general of Texas and a federal prosecutor in the Department of Justice’s Public Integrity Section.

The end of the current session of congress will see other prominent Republican foreign policy hawks depart Congress as well, including Rep. Don Bacon (R-NE), and a new generation of GOP leaders take leadership of key foreign policy committees.

McCaul’s deep-red district — redrawn to be even darker red in the next election cycle — is expected to remain in Republican hands.
