The 88th United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, D.C., from January 3, 1963, to January 3, 1965, during the final months of the presidency of John F. Kennedy, and the first years of the presidency of his successor, Lyndon B. Johnson. The apportionment of seats in this House of Representatives was based on the 1960 United States census, and the number of members was again 435 (it had temporarily been 437 in order to seat one member each from recently admitted states of Alaska and Hawaii). Both chambers maintained a Democratic majority - including a filibuster-proof supermajority in the Senate - and with President Kennedy, the Democrats maintained an overall federal government trifecta.
