Trump asked about the left wing hate groups like BLM, antifa, Occupy Wall Street - all funded, organized, violent left-wing hate groups.  Democrats have been hiding behind the mob since they lost the civil war.  They organized new ones in recent years - same techniques, same people, new names.

Charlottesville would never have happened if the black vice mayor had not decided to pick a fight by removing a statue.  It would never have happened if democrat VA governor McAulliffe and the mayor had not told law enforcement to stand down.  The entire event is similar to Trump campaign events last year where democrat mayors told local law enforcement to stand aside and allow democrat rent-a-mobs to attack and beat Trump supporters leaving his rallies.  San Jose was one such example.

Senator Begich seems just fine with mob violence, as long as it is his guys doing it.  Be careful what you wish for, Senator.  Cheers -
