The Murkowski Wildcard

If Sen. Lisa Murkowski decides to jump ship and vote with Susan Collins and Mitt Romney to allow new witnesses in the impeachment trial, Democrats still lack the votes they need since a 50-50 tie would mean the witness motion has failed without a majority. 

However, the Washington Post says “uncertainty remains surrounding what could happen if there is a 50-50 tie on the motion to hear more evidence, a vote that will occur Friday evening. Republicans have been warily eyeing Chief Justice John Roberts, hoping he would not weigh in to break a tie if three GOP senators side with Democrats on the effort,”

Earlier for members: Yes, the Chief Justice can break a tie on witnesses.
