President Obama says Donald Trump risks "flying blind" if he follows through with his promise not to have daily briefings from the intelligence services.

Mr Trump is only having the briefings once a week at the moment, and his relationship with the CIA and other agencies has got off to a rocky start.

The President-elect has dismissed a CIA report which accused Russia of being behind cyberattacks aimed at undermining Democratic Party opponent Hillary Clinton, and he attacked agencies' work on Iraq.

But Mr Obama told Comedy Central's The Daily Show: "I think the President-elect may say one thing and do another once he's here because the truth of the matter is it's a big complicated world.

"It doesn't matter how smart you are. You have to make the best information possible to make the best decisions possible.


"And my experience with our intelligence agencies is they are not perfect. They would be the first to acknowledge that.

"But they are full of extraordinary, hard-working and patriotic and knowledgeable experts, and if you are not getting their perspective, their detailed perspective, then you are flying blind."

Mr Trump told Time magazine he did not believe Russia interfered in the election by hacking Democratic Party organisations and leaders.

"That became a laughing point, not a talking point, a laughing point," he said. "Any time I do something, they say, 'Oh, Russia interfered.'"

And on the intelligence agencies he said: "These are the same people that said Saddam Hussein has weapons of mass destruction."

Mr Obama has now called for a review of cyberattacks on the Democratic National Committee (DNC) and foreign intervention during the election campaign and wants a full report before he leaves office on 20 January.

"We determined and announced in October that it was the consensus of all the intelligence agencies and law enforcement that organisations affiliated with Russian intelligence were responsible for the hacking of the DNC materials that were being leaked," said Mr Obama.

"So that was a month before the election. This was not a secret."

He says he wants to prevent similar interference in future elections.

"The President-elect in some of his political events specifically said to the Russians, hack Hillary's emails so we can finally find out what's going on and confirm our conspiracy theories," Mr Obama told Daily Show host Trevor Noah.

"What is it about the state of our democracy where the leaks of what were frankly not very interesting emails that didn't have any explosive information in them ended up being an obsession, and the fact that the Russians were doing this was not an obsession."

Mr Trump has tweeted that if he had accused the Russians of cyberattacks it would have been dismissed as a conspiracy theory.

Russia has always denied accusations that it interfered in the US election.
