Democratic senator to force vote requiring Roberts to weigh in on witnesses

The move comes as GOP senators are increasingly confident they will have the votes to block witnesses from being called.

If Democrats are able to muster four GOP votes to allow witnesses, both sides could then make motions for specific individuals and documents. Under the rules resolution, the Senate would vote on the motions.

But Van Hollen's effort would let Roberts issue subpoenas if he thinks a motion is relevant. The Senate, if it disagreed with his decision, could still overrule him with a simple majority.

"A fair trial includes relevant documents and witnesses. And in a fair trial the judge determines what evidence is admitted," Van Hollen said in a statement. "My motion ensures the Chief Justice will serve the same role as a judge in any trial across our country – to allow the Senate access to the facts they need to get to the truth."

The motion, according to text from Van Hollen's office, would require Roberts to issue subpoenas for witnesses or documents requested by either side if he "deems them likely to have probative evidence relevant to either article of impeachment."

Van Hollen would also require Roberts to referee any claims of executive privilege.

“No Republican can question the fairness of this approach – the Chief Justice oversees the highest court in our land and was nominated by a Republican President. And, given his authority to rule on questions of privilege, they should not fear a drawn-out process," Van Hollen said.

"I urge my colleagues to seek out the truth and the facts and to vote in support of my motion. Anything else constitutes an effort to hide the truth," he added.

The plan to force a vote on Friday comes after Democrats tried to get similar language included in the rules resolution passed last week. Their effort was rejected along party lines.

Roberts has, so far, largely taken a backseat in the impeachment proceeding.

With several GOP senators still undecided on calling witnesses, a 50-50 tie still remains open as one possibility; however, GOP senators say they do not expect Roberts would step in and break the tie.
