Fox News' judicial analyst defends Mueller probe: It's his job to 'go down any rabbit hole he finds'

Fox News judicial analyst Andrew Napolitano on Thursday defended the credibility of special counsel Robert Mueller's Russia investigation, noting it's the former FBI director's job to "go down any rabbit hole he finds."

Napolitano was reacting to a Washington Post , published Wednesday, that revealed Mueller is looking into a "secret meeting in the Seychelles" that occurred right before Donald Trump's inauguration. Blackwater founder Erik Prince-whose sister, Betsy DeVos, is Trump's education secretary-attended the meeting with businessman George Nader, an adviser to the UAE who the New York Times is cooperating with Mueller.

"I don't think this impairs the credibility of the Mueller probe," Napolitano said on "America's Newsroom."

"I also think that Bob Mueller on his own can expand his own authority and investigate this," Napolitano said. "The federal regulation promulgated by the Department of Justice and by the Congress ... authorizes Bob Mueller really to go down any rabbit hole he wants."
