A curious day in Congress
The Senate sets out to give DC voters the ability to elect a voting member to the House of Reps, which is blatantly unconstitutional (the Constitution refers to House members in terms of being residents of a State, which DC is not), and compensating the GOP by adding one member from Utah (which, depending on how it is done, is probably unconstitutional as well.
Along the way the Senate adds an amendment repealing most of the DC gun laws. At least that's constitutional.
UPDATE: I dunno who would have standing to challenge the constitutionality. Maybe anyone, maybe no one. I recall back, nearly 30 years ago, Rep. Abner Mikva was confirmed as a judge of the DC Circuit Court of Appeals. The salary for the position had been increased (via an automatic pay raise) during his time as a legislator, so there was a good, if not 100%, argument that he was barred from taking it. Congress passed a bill that specifically said any Congress critter could challenge the appointment in the name of the US. Senator McClure sued -- and the court ruled that he had no standing, despite the enactment. In that case, there was at least a theoretical way to raise the issue ... anytime he was assigned to a panel to decide a case, either side could have objected. But since that would really hack off the court, no one ever did.
