It also notes that passing legislation to give D.C. residents representation would be challenged, and amending the Constitution is likely to be difficult. Instead, it says giving Maryland the land back would be less complicated.

"An alternative to a potentially lengthy and difficult constitutional amendment process is ceding Washington, D.C. back to Maryland, just as an area of 31 square miles that was originally ceded by Virginia was returned to that State by Federal legislation in 1847, thereby ensuring that the portion of Washington, D.C. in Virginia would have Senate and House representation," the resolution reads.

"Accordingly, the District of Columbia would clearly and constitutionally have 2 Senators and a Representative with full voting rights by ceding the District of Columbia to Maryland after Maryland's acceptance of such retrocession, while maintaining the exclusive legislative authority and control of Congress over the National Capital Service Area in the District of Columbia."

Under the bill, the territory of D.C. would be given to Maryland, but control of the National Capital Service Area would not be ceded. The bill very specifically outlines the areas that would still be under the control of the federal government.

The bill would also have the delegate to Congress, currently Eleanor Holmes Norton (D), serve as a full-fledged member of the House. Until House representation is reapportioned, Maryland would also temporarily receive an additional member of Congress.
