WASHINGTON—Centrist Sen. Thom Tillis (R., N.C.) said he won’t seek re-election in 2026, less than 24 hours after he voted against a motion to advance President Trump’s tax and spending megabill, drawing public backlash from the president.

Republican Senator Tillis won't seek reelection in 2026 following his vote against Trump's bill, criticizing Washington's partisan politics and its scorn for independent thinkers.
