On the heels of the general election last week, there’s another important vote on tap this Wednesday in Washington that will greatly impact what President-elect Donald Trump can accomplish during his four years in office: Republicans in the Senate will vote by secret ballot to choose a new leader.

Republican senators will cast a secret ballot on Wednesday, and whoever is elected to replace McConnell will inherit a solid majority in the upper chamber.

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.

Democrat Ruben Gallego has been elected Arizona’s first Latino U.S. senator, defeating Republican Kari Lake and preventing Republicans from further padding their Senate majority. Gallego’s victory continues a string of Democratic successes for the Senate in a state that was reliably Republican for those seats until Donald Trump was elected president in 2016.

Democratic Rep. Ruben Gallego will win a closely watched US Senate seat in Arizona, CNN projects, defeating Republican Kari Lake to become the state’s first Latino senator.
