Jason Chaffetz (R-UT) questions Internal Revenue Service Commissioner John Koskinen during a hearing in the Rayburn House Office Building on Capitol Hill September 21, 2016 in Washington, DC. Despite the lack of evidence against him, Koskinen is facing impeachment threats from conservatives in the House of Representatives for his role in the destruction of computer backups containing thousands of emails sought by Congress in its investigation of political targeting.

Tonight, House Oversight Committee chair Rep. Jason Cheffetz (R, UT-03) wrote a letter to the FBI giving them one week to turn over “memoranda, notes, summaries, [and] recordings” of James Comey’s that may detail President Donald Trump’s attempt to end the FBI investigation of Michael Flynn.

As Chairman, Rep. Chaffetz has the power to subpoena the documents if they do not cooperate.

The letter follows a lurid New York Times report that says Trump asked fired FBI Director James Comey to end the investigation into former National Security Advisor Michael Flynn, saying “I hope you can let this go.”

The story, however, is a reported summary of a phone conversation conducted with FBI officials who have access to Comey’s memos. The New York Times has not acquired the memos themselves; only other FBI officials have seen them.

Comey allegedly wrote the memo following a conversation with Trump on the day after Flynn resigned. The memos say Trump told Comey:

“I hope you can see your way clear to letting this go, to letting Flynn go. He is a good guy. I hope you can let this go.”

“While the President has repeatedly expressed his view that General Flynn is a decent man who served and protected our country, the President has never asked Mr. Comey or anyone else to end any investigation, including any investigation involving General Flynn. The President has the utmost respect for our law enforcement agencies, and all investigations. This is not a truthful or accurate portrayal of the conversation between the President and Mr. Comey.”

Trump himself has not weighed in on the story to confirm or reverse the White House’s statement, as he has with this week’s revelation that he revealed sensitive intelligence to Russian diplomats.

Reaction to the New York Times report was swift, with Speaker of the House Paul Ryan and Republican members of Congress expressing unease and calling for Comey’s immediate testimony.

Speaker Ryan spox on Comey memo: "We need to have all the facts, & it is appropriate for the House Oversight Committee to request this memo"
