Bill Clinton slammed FBI director James Comey for what he calls the 'the biggest load of bull I've ever heard' Comey's testimoney regarding Hillary Clinton's emails

'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,' Bill Clinton said of his wife on Friday in Las Vegas

'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 the crowd.

'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?' he said as he made the case for his wife.

However, some Republicans are criticizing Clinton's remarks and calling his words 'spin'.

Wisconsin representative Sean Duffy told Fox and Friends: 'He’s just trying to spin Hillary out of trouble, and it doesn’t work.'

'For Bill Clinton to come out now and say that this is a bunch of "bull", why then did he have this secret meeting with Loretta Lynch on the tarmac in Arizona to make sure he could tap down any kind of prosecution that comes from the DOJ.

'If he wasn’t concerned about Hillary Clinton and her scandal about the email he wouldn’t have had to have that secret meeting.'

Hillary Clinton has been taking heat for using a private server for her emails since it was revealed last year.

An FBI investigation deemed that no charges would be brought against Clinton for the use of the private server.

Bill Clinton continued to argue that there is no way Hillary Clinton ever put national security at risk during her time as secretary of state.

'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?
