Splitting Up Together star and recently published author Jenna Fischer took to social media to today to describe an event Tuesday night in Indiana at which student protesters interrupted her book-signing and Q&A event.

The Office alum said she was alerted by reps of DePauw University in Greencastle that there might be demonstratons during her presentation — and indeed there were. There have been a number of recent incidents on and off campus involving racial, homophobic and anti-Semitic slurs and other divisive ugliness. She wrote that she “could feel the pain, sadness and fear” coming from the student protesters.

The protest began about 15 minutes into Fischer’s appearance and lasted for about 10 minutes, according to reports. Watch a local TV news story about the incident above, which quotes a DePauw official as saying was a “tough situation” for which school authorities were not prepared.

Fischer said she is donating her fee from the event among the NAACP, the Anti-Defamation League and the Trevor Project.

Here’s how she described what happened as she visited to school near Indianapolis to promote during a book tour for The Actor’s Life: A Survival Guide, followed by a brief video tweeted by someone in the crowd and an example of the hate speech that has surfaced at and around DePauw in recent days:
