The Republican party has chosen their new Senate majority leader, John Thune of South Dakota. Who is this low-key politician, and how will he work with Trump?

United States Senator John Thune won the secret ballot making him the new Republican Senate Leader and the majority leader of the upper chamber in the new Congress.

In the first seriously contested Senate Republican leadership election in decades, three senators are vying to replace longtime GOP leader Mitch McConnell when he steps down from the post at the beginning of next year.
