Evidence Based Information

Rep. Ron DeSantis (R-Fla.) accused John Brennan on Monday of having been a member of the Communist Party during the Cold War, saying that the former CIA director lacks the credibility to discuss President Trump's meeting with his Russian counterpart, Vladimir Putin.

"John Brennan was a disaster as CIA director. He was a disaster as the counterterrorism official. He was a member of the Communist Party during the Cold War," DeSantis said on Fox News.

"So this is not exactly the guy I would listen to about Russia," he added.
