It's unclear which one of the Dems running for President is paying for the violent rioters, but this was posted on Craigslist on Friday telling people they will be paid $15 per hour to protesting at a Trump rally:
To Whom It May Concern:
We will pay $15.00 an hour plus travel (including room and board), clothing, flags, signs, etc. for individuals willing to disrupt Trump rallies throughout the US. If interested please leave your name and a contact number.
