Bernie Sanders is lying when he says his disruptors aren't told to go to my events. Be careful Bernie, or my supporters will go to yours!

Sanders said on Saturday his supporters are not to blame for violence that broke out at a planned Trump rally in Chicago.

"I don't think our supporters are inciting. What our supporters are doing is responding to a candidate who has, in fact, in many ways, encouraged violence," Sanders said at a press conference, according to CNN. "When he talks about ... 'I wish we were in the old days when you could punch somebody in the head.' What do you think that says to his supporters?"

Trump was forced to cancel a rally on Friday night when massive demonstrations sparked scuffles between his supporters and protesters.

During a campaign stop on Saturday, Trump said his supporters "caused no problem."

"They were taunted; they were harassed by these other people — by the way, some represented Bernie, our communist friend," Trump said.
