Administrators at the University of California at Berkeley said Wednesday that they were canceling a speech by controversial conservative commentator Ann Coulter over safety concerns. The decision came after three months in which riots and violent protests have erupted in and around the campus. University officials announced the decision in a letter to a campus Republican group that also invited right-wing provocateur Milo Yiannopoulos, then a Breitbart editor, to speak. Protests led the school to put the campus on lockdown and cancel Yiannopoulos’ speech, prompting President Trump to threaten to cut off federal funds because he said the decision violated Yiannopoulos’ right to free speech. Coulter also said she thought the school was squelching her free speech rights.
