The 7th 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, 1801, to March 4, 1803, during the first two years of Thomas Jefferson's presidency. The apportionment of seats in the House of Representatives was based on the 1790 United States census. Both chambers had a Democratic-Republican majority, except when the Senate held a two-day Special Senate session in order to provide advice to the new President Thomas Jefferson, when there was still a Federalist majority in the Senate.

Senate

The Federalists still controlled the Senate when they held a two-day special Senate session in March 1801, which was called by outgoing President John Adams so that the Senate could provide advice to the new President Thomas Jefferson, but by the time Congress began its first regular session in December 1801 to start official business, the Democratic-Republicans had gained Senate control.
