FBI Director Christopher Wray says President Trump has never made any requests of him regarding the federal Russia probe, but does not deny reports that he threatened to resign after he was encouraged to fire people under his charge.

“He’s never asked me to do anything with the Russia investigation,” Wray told NBC News’ Pete Williams in an interview clip shown on Tuesday.

Wray's assertion stands in stark contrast to that of former FBI Director James Comey, who was fired by Trump last year. Comey testified before the Senate Intelligence Committee last June that Trump requested his loyalty and pressed him to drop the investigation into former national security adviser Michael Flynn.

It was after Comey's ouster that the Washington Post reported Mueller had expanded his investigation to look at possible obstruction of justice.

Trump has long called the Russia investigation a "witch hunt," but the White House rejects reports that say he has talked about firing Mueller.

During the same interview with NBC News, Wray declined to refute reporting earlier this year that said he threatened to resign from his post amid pressure to fire people.

“You know, I have been very clear — from the minute I was nominated — to the minute I walked in the door to countless opportunities since then, that I am unwaveringly committed to doing this job by the book, independently — following our rules and our processes free from political or partisan influence,” Wray said.

“So, it sounds like you’re saying those reports are not wrong,” Williams said.

“I’m not going to talk about specific conversations,” Wray said.

In January, reports emerged that Wray had warned he would step down as he was urged by Trump and Attorney General Jeff Sessions to fire his deputy, Andrew McCabe. That effort was reportedly diffused after White House counsel Don McGahn told Sessions firing McCabe was not worth it if it meant Wray would leave.

However, McCabe was fired on Friday by Sessions -— less than 48 hours before he was able to retire with a full pension. He has been under internal investigation over the FBI's role in federal inquiries during the 2016 election.

Wray assumed office as the new FBI director in August 2017, after being confirmed by the Senate.
