( CNN) The showdown continued Thursday between the University of California, Berkeley, and Ann Coulter over if and when the conservative firebrand will speak at the famously progressive school.

Citing safety concerns, administrators on Wednesday postponed Coulter’s scheduled April 27 appearing, saying it needed more time to find a “suitable venue.”

But Coulter was not having it. In a Twitter rampage and a Fox News appearance, she accused the school of canceling the event and swore to speak as planned.
