*Nick Cannon says he will not apologize to Georgian Court University in New Jersey after the private, Roman Catholic school called his recent performance there “offensive” and demanded he apologize.

“I ain’t apologizing for s— LOL… wait, I’m sorry your university doesn’t believe in freedom of speech!!!” Cannon, 36, tweeted on Tuesday night, alongside a screenshot of an email sent to the “GCU Community” by the university’s president, Dr. Joseph R. Marbach.

In the email, Marbach wrote of the university’s “profound disappointment with Nick Cannon.”

“Mr. Cannon blatantly disregarded the terms of our contract and much of his act ran counter to what we stand for at GCU,” he continued. “While comedy often explores serious social issues in ways that are fun and thought-provoking, Mr. Cannon’s act crossed the line. His words were offensives and do not represent our Mercy core values.”

Further, Marbach said the school was “deeply sorry” and has “demanded an official apology from the artist and his representatives.”

Cannon’s performance during the GCU Reunion & Homecoming Weekend 2017 on Saturday, Sept. 20, was announced as a “Comedy Showcase featuring Nick Cannon & Friends” at Lakewood’s Strand Theatre.

In a statement to PEOPLE, Marbach said, “We believe that Mr. Cannon’s performance raised some valuable, thought-provoking topics in his show. The event took place over our reunion weekend and many older alumni were invited to the show alongside of our current students.”

“Because of the anticipated nature of the audience and the context of being a Catholic university, we asked Mr. Cannon to avoid vulgarity and explicit sexual content in his performance,” said Marbach. “Unfortunately, he repeatedly chose to ignore this request.”
