President Donald Trump doesn’t have recordings of his conversations with then-FBI Director James Comey, according to a person familiar with the matter, capping weeks of speculation about whether such tapes exist.

Trump himself raised the question of whether he was taping his Oval Office conversations when, days after firing Comey on May 9, he blasted out a series of tweets suggesting the existence of tapes as a way to try to deter the ousted FBI chief from talking to reporters.

“James Comey better hope that there are no ‘tapes’ of our conversations before he starts leaking to the press!” Trump wrote. He concluded with a tweet calling the investigation into Russian interference in the election and his campaign’s possible involvement a “witch hunt,” asking, “when does it end?”
