A joint session of the United States Congress is a gathering of members of the two chambers of the bicameral legislature of the federal government of the United States: the Senate and the House of Representatives. Joint sessions can be held on any special occasion, but are required to be held when the president delivers a State of the Union address, when they gather to count and certify the votes of the Electoral College as the presidential election, or when they convene on the occasion of a presidential inauguration. A joint meeting is a ceremonial or formal occasion and does not perform any legislative function, and no resolution is proposed nor vote taken.

In the United States, the Electoral College is the group of presidential electors that is formed every four years for the sole purpose of voting for the president and vice president. The process is described in Article II of the U.S. Constitution. Each state appoints electors using legal procedures determined by its legislature, equal in number to its congressional delegation totaling 535 electors. A 1961 amendment granted the federal District of Columbia three electors. Of the current 538 electors, a simple majority of 270 or more electoral votes is required to elect the president and vice president. If no candidate achieves a majority there, a contingent election is held by the House of Representatives to elect the president and by the Senate to elect the vice president. Federal office holders, including senators and representatives, cannot be electors.
