The land covered by the District of Columbia has not been part of any state since before Maryland donated the land to the federal government on September 9, 1791 to be used as part of the federal district (the rest of the federal district was returned to Virginia in 1847).
The District of Columbia originally consisted of land donated by Maryland and Virginia. The Virginia land (the area of Alexandria) was returned in 1846. This was by the request of those in Alexandria and Virginia who complained about Congress's neglect of the community. It was also partly due to the move to outlaw slavery in the District of Columbia, which occurred in 1850.
The land for state capitol buildings in many states was often donated by influential local figures or organizations. Notably, in the case of the District of Columbia, the land was ceded by the states of Maryland and Virginia in the late 18th century to establish the nation's capital. Additionally, various state capitols have unique histories regarding land acquisition, with some being donated by landowners or local governments.
The District of Columbia was formed from land from Virginia and Maryland.
The state of Maryland donated land to build the nation's capital in Washington, D.C. The capital of the United States before this was Philadelphia, Pennsylvania. John Quincy Adams was the first President of the United States to sleep in the White House but for only a short time before his term was up.
The white house is the District of Columbia which is in both Maryland and Virginia.
The District originally was 100 sq. mi. from land donated from Maryland and Virginia. Virginia took its land back in 1846. The 61 sq. mi. that remains is from Maryland.

Washington DC is in the District of Columbia, which is not a state but land ceded by surrounding states.
The city itself is called Washington. Washington is not in a state; it is located in a district called the District of Columbia (that is where the DC in Washington, DC comes from). It is between Maryland and Virginia; all the land in the District of Columbia once belonged to Maryland.
