From the July 20 edition of Fox News' Hannity:
NEWT GINGRICH: The Mueller investigation has so many conflicts of interest, it's almost an absurdity. The law firm he comes from gave 99.81 percent of its donations to Hillary Clinton last year. That’s right, .19 of 1 percent went to Donald Trump. The people that he’s been hiring are all anti-trump lawyers. Several of them have very bad records of hiding information from the defense, and one case was rebuked by the Supreme Court in a 9-0 vote. 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 think that, I don't understand why the House and Senate Judiciary Committees aren't investigating a lot of this stuff. 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 a very reasonable to say this is a very dangerous witch hunt that Mueller keeps expanding it because he can't find anything in the original charge. He's not going to find anything about Trump and Russia, and yet he's hired all of these guys who have given up their very expensive law services to come out and try to get somebody and they're going to eventually find somebody to prosecute because there are too many lawyers being paid too much money for them to go home having accomplished nothing.
