Senate Republicans emerged from a closed-door caucus meeting on Tuesday voicing renewed confidence that they will bypass a nasty witness fight in the impeachment trial.

“We’re kind of confident,” Thune added.

Democrats will need four Republican votes in order to call for additional witnesses. Both sides would then make motions for specific individuals, and the Senate would vote on whether to call them.

Underscoring the urgency of the caucus discussion, Senate Republicans met Tuesday only hours after their normal closed-door caucus lunch.

Though Thune and Barrasso signaled leadership is more confident about the possibility that Republicans could avoid calling Bolton or other witnesses, several other GOP senators signaled no decisions were made during the caucus meeting.

The indecision of the handful of GOP senators underscores that, despite public confidence, McConnell still does not have a lock on 51 votes to block witnesses.

Tuesday's gathering, according to GOP senators, was to check the temperature of the caucus as a whole as Republicans face intense external pressure to call Bolton.

"We're still talking. Everybody is taking this very seriously. ... I know those conversations are continuing," Cornyn said. "I think we'll all just have to wait for Friday."

Calling witnesses would put a spotlight on a messy fight within the Senate Republican Conference. Conservatives are warning that if Republicans vote to help call Bolton, they will try to subpoena Hunter Biden, Joe Biden and the whistleblower.

When a reporter noted that it sounded like Graham thought there were going to be witnesses, he responded, "I would not say that. I would not take that from what I just said. ... We'll see Friday."

"I feel good. I feel good that we're in a good spot in terms of ending trial sooner rather than later," he added.
