It met in Washington, D.C., from January 3, 1965, to January 3, 1967, during the second and third years of Lyndon B. Johnson's presidency. The apportionment of seats in the House of Representatives was based on the 1960 United States census.
Both chambers had a Democratic supermajority, and with the election of President Lyndon B. Johnson to his own term in office, maintaining an overall federal government trifecta. This is the last time Democrats or any party had a 2/3rd supermajority in the Senate.
