Trump's White House lawyers clashed with House Judiciary Committee Chairman Jerrold Nadler (D-N.Y.) late Tuesday night after Nadler said that the president and Republicans were "afraid" to let former national security adviser John Bolton John BoltonDiplomacy with China is good for America The Hill's Morning Report - Sponsored by The Air Line Pilots Association - Pence lauds Harris as 'experienced debater'; Trump, Biden diverge over debate prep DOJ launches probe into Bolton book for possible classified information disclosures MORE testify because "they know he knows so much."

White House legal counsel Pat Cipollone hit back at Nadler shortly after, accusing him of making false allegations.

"You don't deserve and we don't deserve what just happened," Cipollone said, addressing the senators. "The only one who should be embarrassed, Mr. Nadler, is you."

The back-and-forth led Supreme Court Chief Justice John Roberts, who is presiding over the trial, to reprimand both sides.

Roberts said they were "addressing the world's greatest deliberative body" and that they should watch what they say.

"I do think those addressing the Senate should remember where they are," Roberts said.

The White House defense team and House impeachment managers were in the midst of debating a Democratic amendment to the rules resolution on Tuesday that sought to have Bolton testify.

The measure was eventually rejected in a party-line vote.
