Congressman Peter King is calling for an investigation into whether CIA Director John Brennan withheld information from Congress while leaking findings to the media.

King, a Republican of New York, questioned recent leaks from the intelligence community about whether the Russians used hacking to influence the American elections in Donald Trump's favor.

'We have supposedly [CIA Director] John Brennan leaking information to The Washington Post, to a biased newspaper like The New York Times — findings and conclusions that he's not telling the [House] Intelligence Committee,' said King, a former chairman and current member of the House Intelligence Committee, to ABC News' Martha Raddatz on 'This Week.'

In the past week, sources in the intelligence community confirmed that a secret CIA assessment of the hacks on the DNC and Hillary Clinton campaign chair John Podesta found they were orchestrated by Russia to help Trump win.

And on Saturday the FBI, which previously demurred when asked it if agreed, was now on-board with the assessment.

Yet the leaks, which did not name Brennan or FBI Director James Comey as sources, did not convince King, a senior Republican leader in Congress.

'There should be an investigation of what the Russians did, but also John Brennan and the hit job he seems to be orchestrating against the president-elect,' King told Raddatz.

'I'm not saying it didn't happen,' King added of the supposed hacking.

'I'm just saying we've been given no evidence on it, when we have these stories mysteriously appearing in the newspaper.'

Rep. Adam Schiff, D-California, said King's criticism against Brennan is unjustified.

'He has done a remarkable job at the agency,' Schiff told Raddatz on 'This Week.' 'I don't think he's trying to politicize this in any way.'

'I do think there's a consensus among the top leadership in the intelligence community, not only of who was responsible, but why,' Schiff added.

'And I think when the review is released by the administration within the next two or three weeks, I think the American people will see that.'

Schiff also said it was 'deeply damaging' for the president-elect to cast doubt on the intelligence capabilities of the country he was elected to lead.

'For the president-elect to continue to give the Russians deniability is deeply damaging to the country,' Schiff told Raddatz.

'He is doing damage to himself and to his ability to lead the country when he becomes president — we are going to have a national security crisis at some point,' he added.
