Green Party nominee Jill Stein was escorted off the Hofstra University campus Monday night, after protesting that she wasn’t invited to the debate between Hillary Clinton and Donald Trump.

“We were on our way to an interview with @MSNBC when we were stopped by Hofstra security and Nassau County police just now,” Stein tweeted Monday afternoon. “We were immediately escorted off of the Hofstra campus after the press conference just now and told not to do any more press.”
