It is amazing how unfamiliar with or contemptuous of the Constitution Joe Biden and the rabid Democrats are.
The Constitution explicitly states that Washington DC is not to be part of any state and is administered by Congress. I guess they are trying to get around that by having the proposal keep a few blocks around the Capitol as the national capitol, but that is semantics and I hope the Supreme Court would step in.
I would also point out that the land for DC was donated by the state of Maryland expressly to be part of the national capitol. If the land were ever to not be part of the capitol anymore then it would have to be returned to the state of Maryland. And all the residents in that area can start paying a state income tax, like the rest of us.
