In the United States House of Representatives, the District is represented by a delegate, who is not allowed to vote on the House floor but can vote on procedural matters and in congressional committees. D.C. residents have no representation in the United States Senate. The Twenty-third Amendment to the United States Constitution, adopted in 1961, entitles the District to three electoral votes in the election of the President and Vice President of the United States.The District's lack of voting representation in Congress has been an issue since the capital's founding. Numerous proposals have been introduced to change this situation, including legislation and constitutional amendments, returning the District to the state of Maryland, and making the District into a new state. All proposals have been met with political or constitutional challenges and there has been no change in the District's representation in the Congress.
