Police and university officials said they were bracing for possible trouble whether Coulter comes to campus or not, citing intelligence and online chatter by groups threatening to instigate violence. In emails to The Associated Press, Coulter confirmed Wednesday that her planned speech on illegal immigration, followed by a question-answer session, was canceled. Efforts by the university to cancel or delay the event dealt a blow to Berkeley's image as a bastion of tolerance and free speech. Berkeley's reputation as one of the country's most liberal universities, in one of America's most liberal cities, has made it a flashpoint for the nation's political divisions in the era of Donald Trump. The Berkeley College Republicans and the Young America's Foundation, a conservative group that had helped book Coulter's campus speaking events, both pulled their support Tuesday citing fears of violence.
