"You know, I think she's been at the State Department now for almost two years, she's traveled extensively," he said CBS's "Face the Nation."

"I don't know her well," he added. "I don't know much about her work and I know she's been the spokesperson at the State Department."

He added that he's not sure if Nauert has the "detailed knowledge of foreign policy to a level that will allow her to be successful at the United Nations."

"I don't know," he said. "I need to meet with her. She needs to go through our committee and answer questions and then I'll be able to make a judgment on it."

Democrats have argued that Nauert, a former Fox News anchor, is inexperienced.
