Now in his fourth term, Roy is a prominent member of the House Freedom Caucus, a conservative faction that wields strong influence in the narrowly divided House. He was a central player this summer in the negotiations around President Trump's big tax bill.
Roy enters an increasingly crowded Republican primary field to succeed Attorney General Ken Paxton, who is challenging Sen. John Cornyn in the Republican primary next year.
“Texas is under assault — from open-border politicians, radical leftists, and faceless foreign corporations that threaten our sovereignty, safety, and our way of life,” Roy said in a statement. “It’s time to draw a line in the sand."
