President-elect Donald Trump has backed Wikileaks founder Julian Assange in casting doubt on intelligence alleging Russian meddling in the US election.
Assange said Russia was not the source for the site's mass leak of emails from the Democratic Party.
The president-elect has repeatedly refused to accept the conclusions of the US intelligence community.
Several US agencies including the FBI and the CIA believe Russia directed hacks against the Democratic Party and the campaign of its presidential candidate Hillary Clinton.
The FBI and CIA say information, released through Wikileaks and other outlets, was intended to help Trump win the election.
On Tuesday evening, Trump said an intelligence briefing he was due to receive on the issue had been delayed but US intelligence officials insisted there had been no delay in the briefing schedule.
