 Weinstein organized a group of JDL members and supporters to go to Washington, D.C. in March 2017 to counterprotest against anti-Zionist groups protesting the annual American Israel Public Affairs Committee (AIPAC) conference, resulting in several brawls.At least two Canadian JDL supporters have been indicted as a result of alleged violence outside the conference.Yosef Steynovitz was charged with one count of assaulting a man with a dangerous weapon, one count of assaulting a second man, and one count of assault with a hate crimes enhancement for causing significant bodily injury in relation to the beating of Kamal Nayfeh, a 55-year-old Palestinian-American community college teacher who was reportedly walking to the conference when he was attacked.
