Bill Clinton is accusing the FBI director of serving up “the biggest load of bull I’ve ever heard” — marking the first significant public comments from the husband of the Democratic nominee on the scandal that’s plagued his wife’s campaign for over a year.

“First of all, the FBI director said, when he testified before Congress, he had to amend his previous day’s statement that she had never received any emails marked classified,” Clinton told journalists at an Asian American Journalists Association meeting in Las Vegas on Friday, making a strong defense for Hillary Clinton.

He added, “They saw two little notes with a ‘C’ on it — this is the biggest load of bull I’ve ever heard — that were about telephone calls that she needed to make. The State Department typically puts a little ‘C’ on it to discourage people from discussing it in public in the event the secretary of state, whoever it is, doesn’t make a telephone call. Does that sound threatening to the national security to you?”

Hillary Clinton has been under fire since it was discovered last year that she exclusively used her own server to conduct all her work related email on.

On Friday, Bill Clinton went on to say it is inconceivable his wife was threatening national security.

“Do you really believe there are 300 career diplomats because that’s how many people were on these emails, all of whom were careless with national security? Do you believe that? Forget about Hillary, forget about her. Is that conceivable?”
