Associates of Donald Trump may have colluded with Russia during the election campaign, former Clinton campaign Chairman John Podesta alleged Sunday, but Trump spokeswoman Kellyanne rejected the possibility.

Podesta, in his first interview since Democrat Hillary Clinton was defeated by the Republican president-elect, told NBC’s “Meet the Press” he doesn’t think Trump was involved but said electors have a right to know what happened before the Electoral College meets Monday.

"It's very much unknown whether there was collusion," Podesta said. "What did Trump Inc. know? When did they know it? Were they in touch with the Russians?"

U.S. intelligence agencies have concluded Russia was behind the hacking of email accounts belonging to Podesta and the Democratic National Committee to try to turn voter sentiment in Trump’s favor. Trump has rejected the conclusion, ridiculing the idea.

"The Russians were trying to elect a lap dog," said Podesta, adding the FBI had contacted him only once about the hacking, two days after WikiLeaks started releasing his emails.

Conway told CBS’s “Face the Nation” the idea that the campaign was colluding with Russia was ridiculous, calling it “inaccurate and false … dangerous. And it does undermine our democracy."

A top Russian official told CBS last month there had been contact with the Trump campaign. President Barack Obama said last week it was likely Russian President Vladimir Putin was at least aware of the hacking, if not directly involved. And during the first presidential debate, Trump invited Russia to find the missing emails from Clinton’s private server. Later he said he was just kidding.

Conway called on the CIA to release evidence related to the hacking, something Obama said is unlikely to happen because it would expose how the U.S. tracks such attacks.

"If the CIA Director [John] Brennan and others at the top are serious about turning over evidence ... they should do that," she said. "They should not be leaking to the media, if there's evidence, let's see it."

Former CIA Director James Woolsey told ABC’s “This Week” it will be up to the National Security Agency to draw the final conclusions on the hacking.

“This is really an NSA decision, and if — I think more than anything else. And if NSA is confident that it’s the Russians, then it almost certainly is. Depends on them,” Woolsey said.

Sen. John McCain, R-Ariz., again called for a Senate select committee to be appointed to investigate Russia’s cyberactivities and the impact on the election, despite the rejection of such a panel by Senate Majority Leader Mitch McConnell, R-Ky. McCain told CNN’s “State of the Union” there was “no doubt” about Russian interference.

“The question is now, how much and what damage? And what should the United States of America do?" McCain said, adding, however, he’s seen no evidence the Russian interference actually had a major impact on the election.

"We need to get to the bottom of this. We need to find out what was done."

Clinton has blamed her election loss on the Russians.

"And this is something every American should be worried about," Clinton said in remarks Thursday to campaign donors. "You know, we have to recognize that, as the latest reports made clear, Vladimir Putin himself directed the covert cyberattacks against our electoral system, against our democracy, apparently because he has a personal beef against me."
