"The Mueller investigation has so many conflicts of interest, it's almost an absurdity," Gingrich said. "The law firm that he came from, gave 99.81% of its donations to Hillary Clinton last year."

"That's right, .19 of 1% went to Donald Trump," he said.

"The people that he's been hiring are all anti-Trump lawyers. It's hard to understand why he would assemble such a team unless it was a deliberate effort to go after the president and the president's team. I don't understand why the House and Senate Judiciary Committees aren't investigating a lot of this stuff," Newt said.

He continued: "The point you made about leaks is a perfectly good example. The leaks have to be coming from inside Mueller's team. So who's leaking? Why is nothing being done about it? Why are people not being fired? I think it's very reasonable to say that this is a very dangerous witch hunt that Mueller keeps expanding because he can't find anything in the original charge. "
