(CNN)Former FBI Director James Comey wrote in a memo that President Donald Trump asked to end to the investigation of national security adviser Michael Flynn, according to a source familiar with the matter.
Comey was so appalled by the request that he wanted to document it, the source said. Comey shared it with FBI senior officials, according to the source.
“I hope you can let this go,” Comey wrote, quoting the President. CNN has not viewed the memo but the source described it to CNN.
The memo is the clearest sign yet of potential interference by Trump with the investigation into whether members of his campaign team colluded with Russian officials.
Writing the memo was “not out of character,” especially if he was concerned about the legality or moral issues, according to a former Justice Department official.
The New York Times first reported news of the memo.
Multiple White House officials refuted the claim on Tuesday, including one who said a “conversation of that nature” did not happen.
