US President Donald Trump has said he did not make recordings of his private conversations with fired FBI director James Comey, despite previously hinting otherwise.
He tweeted on Thursday: "I did not make, and do not have, any such recordings."
Mr Trump added he had "no idea" whether other tapes or recordings exist.
The president has disputed Mr Comey's assertion that he asked the former FBI director for a pledge of loyalty during a dinner meeting they had.
When news of Mr Comey's account broke, Mr Trump tweeted that Mr Comey "better hope that there are no 'tapes' of our conversations before he starts leaking to the press!"
Under a post-Watergate law, presidential recordings belong to the people and eventually can be made public. Destroying them would be a crime.
The House committee investigating Russian meddling in the election set a Friday deadline for the White House to hand over any tapes.
When he was fired on May 9, Mr Comey was leading an FBI inquiry into alleged Russian interference in the presidential election and any links between Moscow and the Trump team.
