“I’ve got to be careful,” Obama told “Fox News Sunday” in an interview taped last week.

Obama said Clinton has acknowledged a “carelessness” in managing emails but maintains that she didn't jeopardize national security.

"I continue to believe that she has not jeopardized national security," Obama said.

"There's a carelessness in terms of managing emails that she has owned and she has recognized, but I also think it's important to keep this in perspective. This is somebody that has served her country for four years as secretary of State and done an outstanding job."

He also said Clinton would receive a fair investigation not tainted by politics.

"Nobody gets treated differently when it comes to the Justice Department," Obama said. "Nobody is above the law."
