Senators rebuked Warren in a 49-43 party-line vote, rejecting Warren's push to overturn a ruling by Senate Republicans that she had violated the rules during a Senate floor speech.

Warren needed a simple majority to overturn the ruling by Sen. Steve Daines (R-Mont.), who was presiding over the the Senate during Warren's speech.

The move means the progressive senator won't be allowed to speak from the floor until after the Senate wraps up its debate on Sessions's nomination, expected to occur on Wednesday evening.

The drama on the Senate floor comes after McConnell interrupted Warren's speech, accusing her of breaking the upper chamber's guidelines.

“The senator has impugned the motives and conduct of our colleague from Alabama,” McConnell said from the Senate floor. “I call the senator to order under the provisions of Rule 19.”
