Jewish and Muslim students at Harvard University faced bigotry and abuse as the Massachusetts campus was roiled by protests last year, according to two reports released on Tuesday that found many felt shunned by peers and professors for expressing political beliefs.

Each report combines historical context with emotional testimonies recorded during hours of listening sessions with students, faculty, and staff.

Harvard University President Alan Garber issued an apology and promised reforms after campus reports concluded there had been critical lapses in combating prejudice at the Ivy League institution, particularly against Jewish students.
