Republican presidential candidate Donald J. Trump over the weekend suggested that he would urge his supporters to disrupt campaign events being held by Democratic candidate Bernie Sanders.

After Trump called off a rally in Chicago and blamed Sanders' supporters, the GOP front-runner called for the arrest of people who interrupt his events.

Even thought the Sanders campaign was not involved in shutting down Trump's Chicago rally, the anti-Trump demonstration "was largely organized by supporters of Sanders," according to NBC News.

On Sunday, Trump signaled to his legion of followers that it might be time to express their anger by becoming "disruptors" at Sanders' events.

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

It is Clinton and Sanders people who disrupted my rally in Chicago - and then they say I must talk to my people. Phony politicians!
