Sen. Tim Kaine, D-Va., said in an interview Thursday that Hillary Clinton would acknowledge the FBI director's claim that she was extremely careless in her handling to classified State Department information, and concede his characterization is accurate.

The FBI's James Comey announced in July that he would bring no charges against Clinton for maintaining private email servers when she worked at the State Department. However, he said at the same press conference that his agency uncovered several troubling details in the course of their investigation.

"Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence that they were extremely careless in their handling of very sensitive, highly classified information," the FBI director said.

On Thursday, Kaine conceded in an interview with CBS News' Norah O'Donnell that Comey had indeed characterized the former secretary of state's actions as "extremely careless."

"I think [Clinton] would acknowledge that," he said.

"She said, 'Look, it was a mistake and I've learned from it and I'd do something different," he added. "Look I think this probably taught a lot of people. Because others have done similar things or been careless in similar ways."

Kaine also insisted in his his interview with CBS News' Norah O'Donnell that the Democratic presidential candidate has told the truth about her private email scandal, and that he trusts she has been forthright with the American people.

"Hillary and I have talked about this personally and we sat down within minutes after I was rolled out as her running mate to do a '60 Minutes' interview and she said, 'I made a mistake. I screwed up and I learned something and I'll do it differently,'" Kaine said.

"That's been the way she's pitched it to me, and I think that's the honest response, and I've heard her say that a number of times," he added.
