Nunes: 'Clear Evidence' of Russia Collusion... by Clinton Campaign & DNC

On "America's News HQ" on Saturday, Rep. Adam Smith (D-Wash.) pushed back on one of the central allegations of a controversial memo on purported government surveillance abuses.

The memo, which was released on Friday by Republicans on the House Intelligence Committee, claims that the FBI and Justice Department relied on the infamous anti-Trump dossier to secure FISA surveillance warrants to spy on Trump campaign adviser Carter Page.

"The warrant was not based on the dossier," Smith said, claiming there was a "mountain of evidence" that Page had been having improper connections with Russian intelligence operatives.

He said there is also abundant evidence of high-ranking Trump officials -- like former Trump campaign chairman Paul Manafort -- having met with Russians during the course of the campaign.

"The dossier was not the key or did not have anything hardly to do with the getting of the warrant against Carter Page," Smith stated, accusing the authors of the memo of "cherry-picking facts."

Host Leland Vittert pressed Smith to provide evidence for his claim that "the memo is not accurate."

"How do you know that? Have you read any of the warrants?" Vittert asked.

Smith said the argument that is advanced by the memo is that the only way the FBI and Justice Department could have obtained a FISA warrant against page is by using the dossier, which he said is "factually false."

"There is a mountain of evidence about Carter Page's connections to Russian intelligence, his trips back and forth to Moscow -- just like with Michael Flynn and a lot of other people -- that had nothing to do with the dossier," Smith said. "That is a known fact."
