Tillis, who is up for re-election next year in battleground North Carolina, voted against advancing a bill for Trump's domestic policy agenda Saturday evening.

Sen. Thom Tillis (R-N.C.), unburdened by having to run for reelection, torched his party's "Big Beautiful Bill."

Senate Republicans employ an unusual accounting tactic to push Trump's tax bill forward, sparking concerns over national debt and the integrity of the Senate filibuster.
