The US Attorney basically said no gun carry in Washington DC.

TLDR-

This syndrome reached an apotheosis of sorts when Jeanine Pirro, best known as a reality TV judge and right-wing blowhard, and now (because of course!) appointed by Trump as U.S. attorney for the District of Columbia, issued this edict: if anyone brings “a gun into the District, you mark my words, you’re going to jail. I don’t care if you have a license in another district and I don’t care if you’re a law-abiding gun owner somewhere else.”
