Fox News Special Report anchor Bret Baier said he couldn't find any Republicans to be interviewed on his show Tuesday night in the wake of reports that President Trump asked former FBI Director James Comey to drop his probe into former national security adviser Mike Flynn.

"We've tried tonight to get Republicans to come out and talk to us, and there are not Republicans willing to go on camera tonight, as of yet," he said in a panel discussion about the story. "We'll see if that changes.

The New York Times wrote Tuesday evening that anonymous officials said Comey wrote a memo outlining Trump's comments about Flynn.

"I hope you can see your way clear to letting this go, to letting Flynn go," Trump said, according to the Times' report of the memo.

Republicans immediately took a cautious stance, and some seemed to acknowledge that Congress will now need to be fully informed about the alleged memo.

House Oversight and Government Affairs Committee Chairman Jason Chaffetz, R-Utah, said he would subpoena the memo if needed.
