The 72nd United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1931, to March 4, 1933, during the last two years of Herbert Hoover's presidency. The apportionment of seats in this House of Representatives was based on the 1910 United States census. The Senate had a Republican majority. The House started with a very slim Republican majority, but by the time it first met in December 1931, the Democrats had gained a majority through special elections.

The Senate Republican Conference is the formal organization of the Republican Senators in the United States Senate, who currently number 49. Over the last century, the mission of the conference has expanded and been shaped as a means of informing the media of the opinions and activities of Senate Republicans. Today the Senate Republican Conference assists Republican Senators by providing a full range of communications services including graphics, radio, television, and the Internet. Its current Chairman is Senator John Barrasso, and its Vice Chairwoman is currently Senator Shelley Moore Capito.
