Since 1973, the United States Congress has devolved certain powers to the council that would typically be exercised by state legislatures, as well as many powers normally exercised by a city council in the rest of the country. However, the Constitution vests Congress with supreme authority over the federal district, and therefore all acts of the council are subject to congressional review. They may be overturned by Congress and the President. Congress also has the power to legislate for the district and even revoke the home rule charter altogether.
