How Can the Results of a Presidential Election Be Contested?

On August 26, 2016 the Congressional Research Service (CRS) published a report entitled "How Can the Results of a Presidential Election be Contested?"  The brief report reveals that challenges to the vote for presidential electors are initially handled in the states since states are the initial and principal authority for the administration of elections within their jurisdictions. The document also reveals how objections can be made when Congress meets in joint session to count the electoral votes. For further information, it also recommends CRS Report RL32717 ("Counting Electoral Votes: An Overview of Procedures at the Joint Session, Including Objections by Members of Congress") and CRS Report RL32611 ("The Electoral College: How It Works in Contemporary Presidential Elections").
