“This is something that we have, like I said, we have thought a lot about this. And the answer is we don’t know the correct way to proceed because of the separation of powers issue,” Nunes said when asked if he would welcome a committee appearance by Roberts.

“I’m not aware of any time where a judge has, for lack of a better term, testified before the Congress,” Nunes said.
