Famed lawyer Alan Dershowitz said Thursday a poster promoting an event of his at the University of California, Berkeley was defaced with a swastika.

"This was posted at the Law School at @UCBerkeley where I spoke yesterday. A swastika is drawn over my face," Dershowitz, who is Jewish, tweeted. "The poster itself is filled with out of context misquotes. I oppose torture in all forms."

The lead-up to Dershowitz's Oct. 11 appearance at UC Berkeley on the topic of "The Liberal Case for Israel" was marred with controversy.

Earlier in October, Dershowitz threatened legal action against the school's provost after the institution prevented him from speaking about Israel at the request of a student organization because, as a "high-profile" speaker, they didn't give the administration eight weeks notice.

That requirement is usually waived for guests invited by the school's departments, Dershowitz told LawNewz.com last month.

"All the departments are all hard left departments," Dershowitz said. "They are much more likely to invite hard left speakers. That results in content-based discrimination."

Dan Mogulof, UC Berkeley's assistant vice chancellor, told the Washington Examiner the school's policy is "content and perspective neutral, with the criteria that trigger the eight-week advance notice requirement based solely on objective measures, such as audience size."

The disagreement was eventually settled when the dean of UC Berkeley's Law School extended Dershowitz an invitation.
