'The Feds' took over the city many years ago.
The District of Columbia has a mayorcouncil government that operates under Article One of the United States Constitution and the District of Columbia Home Rule Act. The Home Rule Act devolves certain powers of the United States Congress to the local government, which consists of a mayor and a 13-member council. https://en.wikipedia.org/wiki/Government_of_the_District_of_Columbia
The District of Columbia Organic Act of 1801 is an organic act enacted by Congress under Article 1, Section 8 of the United States Constitution that formally placed the District of Columbia under the control of Congress and organized the unincorporated territory within the District into two counties: Washington County to the north and east of the Potomac River and Alexandria County to the west and south; left in place and made no change to the status of the charters of the existing cities of Georgetown and Alexandria; and established a court in each of the new counties,[32] with the common law of both Maryland and Virginia continuing to remain in force within the District.[33]
The District of Columbia Organic Act of 1871 repealed the individual charters of the cities of Washington and Georgetown and established a new territorial government for the whole District of Columbia. Though Congress repealed the territorial government in 1874, the legislation was the first to create a single government for the federal district.[34]
The District is not a U.S. state and therefore has no voting representation in the Congress. D.C. residents elect a non-voting delegate to the House of Representatives, currently Eleanor Holmes Norton (D-D.C. At-Large), who may sit on committees, participate in debate, and introduce legislation, but cannot vote on the House floor. The District has no official representation in the United States Senate. Neither chamber seats the District's elected "shadow" representative or senators. D.C. residents are subject to all U.S. federal taxes.[26] In the financial year 2012, D.C. residents and businesses paid $20.7 billion in federal taxes; more than the taxes collected from 19 states and the highest federal taxes per capita.[27]
