Judge Andrew Napolitano, a Fox News senior judicial analyst, said Tuesday that the new broad-sweeping House Judiciary probe into President Donald Trump is "almost literally a witch hunt."

Napolitano appeared on Fox News' "Your World with Neil Cavuto," with host Charles Payne filling in for Cavuto.

"The president is right. This is almost literally a witch hunt. They're looking for anything they can find," Napolitano said.

Earlier in the interview, Napolitano said Congress has "tools with which to do it, unfortunately for the president."

"There's a Supreme Court opinion. And there are cases following it which says basically Congress' investigatory powers are limited to bona fide federal issues," he said. "But that is a very, very broad swath and Congress can investigate anything."

The judge also said the president "can do very little about this."
