President-elect Donald Trump has rejected as "ridiculous" a
CIA assessment that Russian hackers tried to sway the
election in his favour.
He told Fox News the Democrats were putting out the reports
because they were embarrassed at the scale of the election
defeat.
On Friday, CIA officials told US media they had concluded that
Russians hackers were trying to help Mr Trump.
Russian officials have repeatedly denied the hacking
accusations.
Mr Trump said it might have been Russia but it was
impossible to know.
"They have no idea if it's Russia or China or somebody sitting
in a bed some place," he said.
President Barack Obama has ordered a complete review of the
hacks, which targeted emails at the Democratic Party and the
emails of a key aide to presidential nominee Hillary Clinton.
The contents of the emails, passed to Wikileaks and posted
online, were embarrassing to the Democrats and shook up the
presidential campaign.
Senior Republicans have now joined Democrats in calling for a
full investigation.
Republican Senator John McCain, chairman of the Senate
Armed Services Committee, said in a joint statement on
Sunday with top Democrats that the CIA's report "should
alarm every American".
He said in an interview that the congressional investigation
should be more thorough than the one ordered by the White
House.
In October, US government officials pointed the finger at
Russia, accusing it of meddling in the campaign to undermine
the electoral process.
But on Friday, the intelligence community went further when
US media reports said the CIA had "high confidence" that
Russians were trying to influence the election in Mr Trump's
favour.
Russians had hacked the Republican party but chose not to
reveal the contents of what they found, the reports said.
