President Obama today made a "guarantee" the Department of Justice will not give Hillary Clinton preferential treatment over others under criminal investigation.

"I can guarantee ... I can guarantee that not because I give Attorney General [Loretta] Lynch a directive, that is institutionally how we have always operated," Obama said during an appearance on Fox News Sunday. "I do not talk to the Attorney General about pending investigations. I do not talk to FBI directors about pending investigations. We have a strict line and always have maintained it. I guarantee it."

"I guarantee that there is no political influence in any investigation conducted by the Justice Department or the FBI, not just in this case but in any case -- period," he added. "Nobody gets treated differently when it comes to the Justice Department because nobody is above the law."
