What Color is the Constitution in Eleanor Norton’s World?

So says Eleanor Holmes Norton in a press release, opposing exemptions to DCs gun laws for active duty military:

“It is difficult to understand the obsession by some members of Congress with a congressional district that is not their own.  Worse, neither Mr. Gingrey, nor any other member of Congress, would tolerate interference with the local laws of their district.  Neither will I,” Norton said.  “However, Mr. Gingrey’s aim is transparent: to score political points at the expense of residents of the nation’s capital.”

Not their own? I could swear there being something in my copy of the constitution about Congress having the power, “To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the acceptance of Congress, become the Seat of the Government of the United States,” among other things. I don’t know what color the Constitution is in Eleanor Holmes Norton’s world, not even speaking of the sky, but Congress is vested by the constitution with ultimate authority over the District of Columbia, which means what goes on in The District, especially when it comes to constitutional issues, is most definitely Congress’ business.
