House Republican plans to leave Congress after more than 2 decades in office

The long-serving lawmaker noted during an appearance on ABC's "This Week" that he will serve the rest of his current term but is seeking a "new challenge."

McCaul has previously chaired the House Committee on Homeland Security and the House Committee on Foreign Affairs.

"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. 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," he noted.
