Is there any confirmation that the shooter was in any way a leftist, or motivated by left wing ideals? From all I know, it was some random guy who could have been a right winger who thinks Trump is centralizing the government which goes against his Ayn Rand ideology; or it could just be a loonie.

Is he? I haven’t seen any confirmation of that. But I think it said he was shot in the neck from the back, which sounds pretty lethal.
