Hayden told Martha Raddatz on ABC’s “This Week” that it is “unknowable” how much Russians influenced the election and he knocked the former director of national intelligence for claiming otherwise.

“I agree that the Russians affected the election but how much they affected is not just unknown, it is unknowable and so we should stop talking about it,” Hayden asserted. “Donald Trump is the president.”

“You invite folks like us on your show because we’re the fact witnesses, not because we have opinions,” he added.
