The White House already cleaned that one up, said he didn’t mean semis, he meant “assault weapons” which of course is an undefined term.
So, he didn’t mean anything, as usual.
Assault weapons are black, magazine-fed, dangerous-looking, include pistol grips, flash hider,light weight ammo of high muzzle velocity, adjustable stock and have piccatinny rails and are essential to Texas hoghunters. They are light weight and children and seal team members can conveniently shoot them.
Did I miss any features?
