Dershowitz claimed Nadler appeared to have overlooked that Mueller remains open to grilling from Republicans.

“He can’t refuse to answer questions about the FISA application,” Dershowitz said, referring to a request by the FBI to surveil a member of the 2016 Trump campaign under the Foreign Intelligence Surveillance Act (FISA).

“Those are the kind of questions that I think Republicans will be very well prepared to ask. Those are the kind of questions which are currently under investigation by the inspector general whose report we are waiting for. But those are not in any way precluded. So I think that they will regret having called him.”
