The United States Senate has 24 committees and divides its work between them -- 20 of which are permanent committees, four are joint committees with the House, and occasionally, the Senate will create temporary committees.
Each committee has a chairman and a ranking member. The chairmanship is held by a senator from the party of the majority party, while the ranking membership is held by a senator from the party of the minority party.
During this Congress which started in 2019, Republicans hold the majority, meaning the chairs of all committees are Republicans, and the ranking members of all committees are Democrats.
