That is looking far less certainafter reporting on Sundaythat the president’s former National Security Advisor John Bolton is claiming firsthand knowledge that would further corroborate the allegations against him.

Trump quickly denied this.

Bolton has said he would testify at the Senate trial if he is subpoenaed. But senators have put off deciding whether to call new witnesses at the trial until after both House Democrats and Trump’s defense team make their arguments.

In December,Trump was impeachedfor abuse of power and obstruction of Congress.

He has adamantly denied wrongdoing, despite the investigation.

“I NEVER told John Bolton that the aid to Ukraine was tied to investigations into Democrats, including the Bidens,” Trumptweeted on Sunday. “In fact, he never complained about this at the time of his very public termination. If John Bolton said this, it was only to sell a book.”

It’s still uncertain whether the Republican-controlled Senate will allow for Democrats to call Bolton and other top Trump administration officials as witnesses in Trump’s impeachment trial, which will decide whether the president will be removed from office on his impeachment charges.

Bolton’s book,The Room Where it Happened: A White House Memoir, is scheduled for publication on March 17.

The memoir will be “a substantive and factual account of his time in the room where it happened,” according to its description.

The White House refused to cooperate in the months-long investigation in the House.

Sen.Mitt Romney, a Trump critic and former Republican presidential nominee, is among the conservative senators who appear to be leaning toward voting with Democrats to allow witnesses at the trial.

“I think it’s increasingly likely that other Republicans will join those of us who think we should hear from John Bolton,” he told reporters in the Capitol building,according to theTimes.

His lawyers are on day two of their arguments to the Senate.
