Assuming you are referring to the local running of DC, rather than the affairs of the President and Congress...
Article One, Section Eight of the United States Constitution grants the U.S. Congress ultimate authority over Washington, D.C. The District of Columbia did not have an elected city government until the passage of the 1973 Home Rule Act. The Act devolved certain Congressional powers over the District to a local government administered by an elected mayor, currently Adrian Fenty, and the thirteen-member Council of the District of Columbia. However, Congress retains the right to review and overturn laws created by the city council and intervene in local affairs.
