Former Secret Service agent Dan Bongino said Democrats who are pushing Trump-Russia theories are "embarrassing the country."

He said those Democrats should look to members of their own party who say they haven't seen any evidence of such collusion.

Bongino pointed to Senate Intel Committee Ranking Member Dianne Feinstein (D-Calf.), who is not a Trump supporter but said she sees no evidence of collusion.

"Multiple people - credible Democrats - have admitted there's no evidence," Bongino said.

"You are embarrassing the country in order to engage in an ideological fight because you're really upset you lost an election, you clowns," he said.

Bongino also called allegations that the Obama administration openly surveilled civilians "a stain on the history of the country."
