SAN FRANCISCO — Conservative speaker Ann Coulter said she won’t speak at the University of California, Berkeley, on Thursday after losing support from a conservative group that had been seeking to bring her there.

The cancellation comes after nearly a week’s worth of high drama about whether Coulter would address students at the famously liberal campus and home of the Free Speech Movement of the 1960s. University officials, in a news conference on Wednesday, said they were still preparing for protests at the school, despite the speech being called off.
