More than 160 Penn State faculty members signed a letter addressed to university leadership following its plans to scrap the Center for Racial Justice and handling of the Uncensored America event.
Penn State will celebrate its 11th annual Military Appreciation Week with a 5K, a Veterans Day ceremony, and a luncheon.
"Penn State saved my life."
The two-hour "Rally in the Valley" event will begin at 5:45 p.m. on Old Main Lawn.
Far-right activist Jack Posobiec will join Mastriano at the rally.
"We have encouraged peaceful protest, and, while protest is an acceptable means of expression, it becomes unacceptable when it obstructs the basic exchange of ideas," the university wrote.
