Hillary Clinton's campaign manager on Monday rejected the FBI's findings that Clinton sent and received information that was classified at the time on her private email server while she was secretary of state.

Clinton campaign manager Robby Mook defended his boss before an MSNBC panel that said Clinton essentially forced State Department employees to send her classified information on her private server because there was no other way to communicate with her.

"She was forcing everybody that wanted to communicate with her to move out of the classified realm, where you send classified information, and then put it on their own servers and send it to her," host Joe Scarborough asked. "Isn't that even worse?"

But Mook rejected that this is what happened, despite the FBI's public findings.

"You'd understand this, that's simply not true," he said. "You just don't send classified information over the unclassified system."

"You would understand this: the FBI director said she did," Scarborough shot back.

In reply, Mook again ignored the FBI's finding that more than 100 email threads contained classified information that was classified at the time they were sent. Instead, he argued that the FBI didn't believe anyone knew it was classified.

"What the director of the FBI testified was that he did not see a basis to believe that she knew the information in question was classified when she received it," he said. "That's what he said."

That further confused Scarborough, who noted that FBI Director James Comey said explicitly that Clinton and her team were "extremely careless" in how they handled classified information.

"Was I watching an alternate hearing?" he asked. "Because it seems to me he said just the opposite, that a reasonable person would have known?"

It was the second day in a row in which Clinton and her team worked to downplay the FBI's findings, which they've done mostly by leaning on the FBI's decision not to seek criminal charges.

On Fox News Sunday, Clinton herself dodged questions about the FBI's findings, and seemed to insist that there is no problem because there were no signs that any of the information was classified.

Clinton told Fox the FBI "certainly did not believe and had no reason to believe what they were sending was classified."
