The Senate Republican investigators have already spoken to the same people that the FBI will speak to, and have already obtained the same information. The only reason Senate democrat investigators are not named is because they refused to participate, hence they are not interested in the truth.
Bullshit, what a ridiculous assumption. The FBI is a non partisan premier federal agency with thousands of field agents what a stupid assumption to think the senate partisan clowns gather all relevant information. Your leaps of logic are astounding and agenda driven but ok cool.
If the Republicans don't want to ask specific questions for political purposes, then the staffers who work for democrat senators can ask those questions, and all the questions would be asked.
Judge is in hiding what are the questions the partisan investigators asked asked, I can assure you that the FBI will ask more questions than the partisan republican investigators.
Judge has said he is willing to answer whatever questions are asked of him in writing by Senate investigators. You say that "partisan republican investigators" will only ask softball questions, but you fail to mention that democrat investigators can ask all the questions they want, but declined to participate in the investigation.
