Outspoken white nationalist Richard Spencer has been denied a speaking opportunity at the Ohio State University due to public safety concerns.

According to a letter from the university, officials feared Spencer was a "substantial risk to public safety, as well as material and substantial disruption to the work and discipline of the University."

Just mere hours before the administration released this decision on Friday, Spencer's attorneys said they would sue the school if they denied his event.

"The trampling upon the First Amendment by university bureaucrats who have no respect for the right of free speech will in no way be tolerated," Michigan attorney Kyle Bristow wrote.

Ohio's decision comes after Spencer's speech at the University of Florida on Thursday, which went on as planned despite protests. Three of Spencer's supporters were arrested after the speech and face attempted homicide charges after pulling a handgun and firing a round near protesters.
