Moveon.org, Black Lives Matter and many other groups planned and coordinated the activity.
If people think Trump, with his tiny staff and low budget campaign, was able to organize these groups and coordinate these groups, then Trump is a million times smarter and more capable than even his supporters realize.
I think you underestimate Trumps ability to organize events.
Reportedly he put together a fundraiser for wounded troops in 24 hours.
I would also present for thought he has had a small army of marketing, event planning, and other people on staff for some time. He knows who to call or who to have call who needs to be called.
He is also in a position to call in or grant favors to people who work with him.
His resources are far more formidable than if he was just some low-budget fellow with no connections.
AGAIN, PLEASE NOTE THAT AT NO TIME DID I SAY THAT TRUMP HAD ANYTHING TO DO WITH THE EVENTS IN CHICAGO EXCEPT BE THE APPARENT FOCUS OF COMMUNIST GROUPS BENT ON DISRUPTION.
