(CNN) - Rep. Jerry Nadler says he didn't believe President Donald Trump when he denied reports that FBI Director Christopher Wray had threatened to resign.
"First of all, the President is a known liar, so I don't believe anything he says," Nadler, who is ranking member of the House Judiciary Committee, said Tuesday.
"Second of all, the President didn't deny pressuring and urging the FBI to fire the (FBI) Deputy Director, Mr. McCabe, because he didn't approve of his role in the investigation of the President," Nadler told Erin Burnett .
"That is highly improper," he added. "And, again, it's part of a concerted campaign to undermine and to derail an official investigation here."
Trump denied earlier Tuesday that Wray threatened to resign after Attorney General Jeff Sessions pressured him to make staffing changes among the senior ranks at the FBI.
Sessions communicated to Wray, who was hand-picked by Trump and sworn in in August, that he needed a fresh start with his senior team at the FBI, a source familiar with the conversation told CNN. Sessions specifically suggested the bureau's deputy director, Andrew McCabe, and its top lawyer, James Baker, should go.
It is not clear if Sessions explicitly told Wray to fire the two men or simply reassign them, according to the source. Wray, in turn, threatened to quit if McCabe was removed or reassigned from his post, the source said. Baker was reassigned late last year.
Asked Tuesday about reports of Wray's threat to quit, Trump said: "He didn't at all. He did not even a little bit. Nope. And he's gonna do a good job."
