Senate Republicans return to Washington on Tuesday for the first time since they secured the Senate majority to determine who will be the new party leader in the chamber.

Senate Republicans will elect a new leader for the first time in 17 years on Wednesday. Originally thought to be a two-person race, a last-minute addition has turned up the intensity.

Following the election, Republicans will control the Senate with a 53 to 47 majority, but one question remains -- who will become the new Senate majority leader? Outgoing leader Mitch McConnell will remain in Congress but will step aside as the longest serving party leader in history.
