In an interview with the Journal two days after the appearance at UCLA of a spate of posters inscribed with the words #JewHaters that link the campus group Students for Justice in Palestine (SJP) with the terrorist group Hamas, David Horowitz — a well-known right-wing activist and founder of the David Horowitz Freedom Center — for the first time admitted responsibility for the posters.  After they first appeared on the Westwood campus on Feb. 22, the posters also showed up on multiple campuses across the United States.
