"The general I'm worried about is Gen. Flynn," Kaine said.
"Gen. Flynn's trafficking in conspiracy stories that a fourth grader would find incredible suggests either that he's highly gullible or that he's so consumed with malice that he loses his ability to judge what's fact and what's fiction."
Kaine said during the interview that Flynn has shown he doesn't have the judgment to serve in the position.
"Having a national security adviser who has demonstrated either such gullibility or such malice in charge of offering advice to the president on the critical national security issues of the day," Kaine said, "I think, is highly highly troubling."
