UNM law professor Joshua Kastenberg said jurors in the Senate are different than jurors in a traditional courtroom. "Members of the United States Senate have a great deal of immunity while they're working in the scope of their duties," Kastenberg said. "And what I mean by immunity, they're immune from criminal indictments of various natures, immune from civil suits as long as it's within the scope of their duties and so a violation of the oath of office is really going to be addressed by the voters."
