This POS admmited he snuck the guns on a train from California to DC. Can he be charged in any state that the train passed through even if just for illegal transport of guns? Plenty of red states along both major train routes to DC.
Assuming the LEO that was saved by his bullet proof vest wasn’t hit by friendly fire, maybe that is how you try this case. Distance the name Trump from the charges, and the minds of the low IQ, racists DC jurists. Go for the attempted murder of a Law Enforcement officer.
