I am not a Trump fan, but the media, and the Republican Party leaders and hangers-on who are afraid of any candidate whom they don't control, are blaming Trump for the disrupters at his rallies.
The truth is...
These are airheads, thrill seekers, organized by the Bernie Sanders apparatus, MoveOn and Black Lives Matter (funded by George Soros), and a coalition of illegal immigrant advocates, Communist Party, Socialist Party ( large in Chicago ) ... all of this admitted and bragged about on camera. The web pages, forums, and Twitter feeds organizing this socialist violence is public record, up there on the Bernie Sanders web site, on MoveOn.org, etc.
Many of the agitators and demonstrators were recognized by reporters and shown on videotape, as being at the demonstrations in Ferguson, Missouri over the thug being shot when he tried to grab a policeman's pistol, at the riots and looting in Baltimore last year, at the violent protests in Seattle, Portland and New York City.
One of the organizers of the Chicago mob was Bill Ayers, the ghost writer of Obama's book. Ayers is a long-time friend of Obama, one of his mentors. Ayers' and his wife were fugitives from justice for more than two decades, wanted for bombing the Pentagon and crippling an astronaut with a letter bomb. He and Hillary Clinton were involved in the 1968 riots at the Democrat National Convention in Chicago.
