"You know, I think the president's been struggling to regain the moral authority to lead the nation and this doesn't really encourage anyone," Paul said in an interview with Fox News.
"To reappoint or to promote, basically, the person who was guilty of misleading us over the Benghazi tragedy, I can't imagine one, that we would be keeping Ambassador Rice in any significant position much less promoting her to an important position. How are they going to have the authority for people to believe what they're saying when he's promoting someone who directly and deliberately mislead the public over Benghazi?"
Paul's comments in response to Tom Donilon stepping down as national security adviser to President Obama. The White House announced that Rice, currently ambassador to the United Nations, would succeed Donilon.
Donilon officials steps down in July.
