If you stand around DC long enough....you will see the normal Presidential motorcade....anything from five vehicles to a dozen.
No surprises....the two idiots were yelling and using profanity. They got tossed to the ground. They will get some assault charges and probably get six months in jail (my guess).
Just another day in DC. We have idiots like this around the Pentagon bus terminal about once a week. They tend to be juiced up on something....and they just cut loose.
It's a reminder that DC isn't some worldclass city....it's like Bolivia....just one step up maybe, and they speak English (mostly).
