*Indicates that a special session of the House and/or Senate was convened during a Congress. Article II, Section 3 of the constitution provides that the President "may, on extraordinary occasions, convene both Houses, or either of them." This procedure occurs only if the Congress is convened by presidential proclamation. Extraordinary sessions have been called by the Chief Executive to urge the Congress to focus on important national issues. These are separate sessions of Congress, unless otherwise noted.
