Rep. Keith Ellison (D., Minn.) claimed on Friday there was collusion between the Trump campaign and Russia, although he admitted he had no evidence to back his claims. The accusation came during an interview with Alisyn Camerota on CNN's "New Day."

"This is stunning when you think about it. Far worse than Watergate, when you believe a hostile foreign power engaged in an attempt, and with the collusion of the sitting administration to manipulate an election," Ellison said.

"Well you don't know that," Camerota interjected, saying there is no evidence of collusion.

"I'm not saying there was collusion, I'm saying those meetings indicate that there could be, and I think that needs to be investigated," Ellison said.
