WASHINGTON >> Then-FBI Director James Comey wrote in a memo after a dinner with President Donald Trump that the president had asked him to shut down an FBI investigation into ousted national security adviser Michael Flynn, a person familiar with the situation told the Associated Press today.

The person had seen the memo but was not authorized to discuss it by name and spoke on condition of anonymity. The existence of the memo was first reported today by The New York Times.

The memo followed a Jan. 27 dinner between Trump and Comey.

The FBI declined to comment today. The White House denied that Trump had made that request of Comey.

The White House said the New York Times report is “not a truthful or accurate portrayal of the conversation between the president and Mr. Comey.”

The White House said that while the president has repeatedly expressed his view that Flynn is a “decent man,” he has never asked Comey or anyone else to end any investigations involving him.

Flynn was fired after misleading top White House officials about his contacts with Russia.

After the Times broke the story, Rep. Jason Chaffetz, R-Utah, chairman of the House oversight committee, said he will seek copies of any memos Comey wrote about his meetings with Trump. In a tweet, Chaffetz said his “subpoena pen ready.”

On the Senate floor, meanwhile, U.S. Sen. Chuck Schumer, D-N.Y., said, “history is watching” and “the country is being tested in unprecedented ways.”

Schumer said he was “shaken” by the report that Trump asked Comey “to shut down an active investigation into a close political associate.”

Schumer has been urging Deputy Attorney General Rod Rosenstein to name a special counsel to investigate Russian interference into last year’s campaign and ties between Russian and Trump associates, including Flynn.
