Story highlights She was at the university doing press interviews

She was escorted off before she could try to make her way to the debate stage

Washington (CNN) Green Party presidential nominee Jill Stein was escorted off the Hofstra University campus Monday after her prearranged media interviews because she didn't have credentials to be there.

Stein's campaign told CNN that she was at the university doing press interviews and was escorted off after an interview with MSNBC.

"We were on our way to an interview with @MSNBC when we were stopped by Hofstra security and Nassau County police just now. #debatenight" she tweeted.

The Nassau County Police Department told CNN that Stein failed to provide the proper credentials at the university, which led to her being escorted off campus.

"She was on the college campus, we asked to verify for proper credentials, she did not have them, and she was nicely escorted off the campus," a police department spokeswoman said.
