"I do believe, based on their words only,” Beck told Kelly via satellite, “that Russia is trying to take down Hillary Clinton ... to destabilize our election and foment revolution on our streets.”

Beck's comments come on the heels of the release of hacked emails and documents from the Democratic National Committee (DNC) showing party officials actively strategizing against Clinton's primary rival, Sen.

U.S. intelligence officials reportedly have "high confidence" that the Russian government was responsible for the hacking. 

"Russia is trying to do to us right now what we did to them under Ronald Reagan," Beck argued.

"We collapsed the Soviet Union. Putin is going to pay us back."

"Mitt Romney called this and everybody mocked him. We're about to find out that Russia is our biggest foe and our biggest nightmare."

As for Beck predicting Trump would win the election as recently as this May, the Blaze founder and host declined to stick to his guns.

"I've got nothing right during this election," Beck joked.

The appearance is Beck's first on the network since publicly praising Kelly following the news of her cooperation with investigators looking into sexual harassment claims against Beck's former boss, former Fox News CEO and Chairman Roger Ailes.

Ailes resigned on July 21.
