BERKELEY — A scheduled April 27 speech at UC Berkeley by conservative pundit Ann Coulter is off, at least at the university, because university officials say they can’t guarantee the safety of Coulter or anyone else in attendance from possible violence.

It would mark the third cancellation of a conservative speaker’s appearance on the Berkeley campus in 10 weeks, following those of former Breitbart News editor Milo Yiannopolous Feb. 1 and conservative writer David Horowitz on April 15. Violence ensued after the Yiannopolous cancellation.

But the Virginia-based group Young America’s Foundation, on its website Wednesday afternoon, said Coulter’s speech would go on but not at UC Berkeley. That website didn’t list an alternative location.

UC Berkeley Vice Chancellor Scott Biddy and Vice Chancellor for Student Affairs Stephen Sutton sent a letter Tuesday night to the Berkeley College Republicans group, which invited Coulter. Biddy and Sutton said the university wouldn’t be able to protect participants, including Coulter, from the kind of rioting surrounding the planned Feb. 1 speech by Yiannopolous. The UC officials also said the university would work with the group to find an alternative time and date for the often-provocative Coulter to speak on or near the campus.

UC Berkeley spokesman Dan Mogulof reiterated that commitment Wednesday, and said the university should have been part of the planning process for Coulter’s appearance much earlier. It was unfortunate, Mogulof said, that Coulter agreed to come to Berkeley before university officials knew she had been asked.

Proceeding with the speech on campus would have been too risky, Mogulof said, given that UC police had learned that some of the people who clashed violently Saturday at the pro-Donald Trump rally in Berkeley planned to target Coulter’s April 27 appearance.

“We are willing to shoulder an acceptable degree of risk; there’s always an element of risk, but it can be managed with advance planning,” Mogulof said. For the university to defy campus police warnings, he said, would be not an “acceptable degree” of risk. “Timing and location matter.”

Coulter said in a tweet Wednesday that “I acceded to Berkeley’s every silly demand (never made of lib speakers) … Called their bluff & they canceled anyway.” She told the Washington Post on Wednesday she believes her speech “has been unconstitutionally banned” by the “public, taxpayer-supported UC Berkeley.”

Coulter on Wednesday afternoon tweeted that she intends to follow through with her speaking engagement (somewhere) in Berkeley. “Instructing Berkeley student group to spare no expense in renting my speaking venue.”

Mogulof, who called Coulter’s comments and tweets about the university “pretty ludicrous,” said the door is still open to Coulter and to the Berkeley College Republicans to reschedule.

An April 12 appearance by Horowitz was canceled, after university police said that event would have to be scheduled midday and away from the heart of the UC campus, again because of security concerns.
