i'm not going to answer your questions. as jim comey showed, it is a terrible mechanism to prevent someone that wants to testify. would he assert executive privilege. and comey says you can do whatever you want. >> the report is in his head, depending on the questioning that comes forward. the white house says exerts executive privilege, does that immediately go to the supreme court. >> no, i think it is really, ultimately, mueller can show up the next day under subpoena and unless there is an injunction, he can testify in response to their question. >> so they would have to go to court and seek an injunction. >> nothing like that has happened before, so mueller's ultimate weapon here is the ability to go and do that.
