After hearing that Yiannopoulos is planning to name undocumented students at a February 1 speech sponsored by Berkeley College Republicans, thousands of students hold a peaceful protest. But about two hours before the event, some 150 black bloc anarchists arrive and begin throwing powerful fireworks and rocks, smashing windows and attacking Yiannopoulos supporters. Citing public safety, University police cancel the event. On Twitter, President Donald Trump threatens to withhold federal funding from the school because it “does not allow free speech and practices violence on innocent people with a different point of view.”
