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.

Republican Senators Rand Paul, Marco Rubio, Mike Lee and Ron Johnson have all endorsed Scott, as have leading figures in the MAGA movement, including Vivek Ramaswamy and Tucker Carlson. Trump did not endorse any of the senators vying for the position.

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?

The incoming Senate Republican majority made their very first major move, electing South Dakota Senator John Thune as their next leader. The Washington Post's Rhonda Colvin reports from the Capitol.

In an interview with POLITICO Magazine, Liam Donovan, a former GOP political operative and lobbyist who’s a close observer of Capitol Hill, laid out the political landmines facing the candidates to be the next Senate majority leader and the sway that Trump holds — or doesn’t hold — in the contest.

President-elect Donald Trump congratulated Sen. John Thune on winning election to the role of Senate majority leader, declaring that the lawmaker "will do an outstanding job."
