Non denial.
Even if true (and its probably not), they do pay organizers, training, flyers, signs, logistics, and legal support.
Maybe also buying those used cop cars for Antifa to destroy, and the piles of bricks distributed to march locations.
And maybe some 'petty cash' for team leaders to distribute as they see fit.
But literally pay people with specific instructions to riot?
Of course not, that would be illegal.
