Rand Paul frustrated after John Roberts rejects his whistleblower question in Senate impeachment trial

Washington (CNN)Sen. Rand Paul of Kentucky expressed frustration with Republican leadership during the Senate impeachment trial Wednesday night after it was made clear Chief Justice John Roberts would not read his question that named the alleged Ukraine whistleblower, sources with knowledge of the situation said.

The development brought Roberts into an unusual position in the trial, where he has served in large part to guide the proceedings, not to decide or make any rulings on how they proceed.
