Trump says he has no tapes of Comey meetings

US President Donald Trump admitted Thursday he does not have recordings of his private meetings with fired FBI director James Comey, after fueling speculation for weeks of secret Oval Office tapes.

But Trump's belated admissions did little to quell allegations that he has sought to stifle investigations into possible collusion between his presidential campaign and Russian interference in last year's election.

"With all of the recently reported electronic surveillance, intercepts, unmasking and illegal leaking of information, I have no idea whether there are 'tapes' or recordings of my conversations with James Comey, but I did not make, and do not have, any such recordings," Trump said on Twitter.

The admission threw a new twist into allegations, fed by Comey's own claims, that Trump wanted the Federal Bureau of Investigation to pull back on its probe into the Russia scandal.

Those accusations are believed to now be part of an independent Justice Department probe into possible illegal obstruction of the investigation by the president.

Trump's tweet came after weeks of challenges to the White House to prove the assertion that he might have recordings of his conversations with the former FBI chief, whom he fired on May 9.

Facing a slew of criticism for sacking the man investigating the Russia scandal, Trump warned Comey there could be retribution if he revealed anything of their private conversations.

"James Comey better hope that there are no 'tapes' of our conversations before he starts leaking to the press!" Trump tweeted on May 12.

That claim quickly raised concerns that Trump, like some US presidents in the past, was secretly recording all of his conversations in the White House.

And it took on more weight when Comey leaked out his own private memorandums of several discussions with Trump, in which he described the president as improperly pressuring him over the Russia probe.

In a June 8 hearing in Congress, Comey described several meetings with Trump and said he in fact hoped the tapes do exist, as they would support his account of their discussions.

"I've seen the tweet about tapes. Lordy, I hope there are tapes," he told the Senate Intelligence Committee.

Democrats had demanded Trump come up with the tapes as they sought support for allegations of illegal obstruction.

Democrats sitting on the House Intelligence Committee that is investigating Russian interference in the election and possible Trump campaign collusion had threatened to issue a subpoena if the White House failed to turn over the supposed tapes of Comey discussions by June 23.
