(JTA) – The presidential campaign of Democratic candidate Bernie Sanders has apologized for ejecting members of a pro-Palestinian/anti-Israel student group from a rally in Boston. The incident occurred Saturday night, Oct. 3 at a large Sanders rally at the Boston Convention and Exhibition Center, where members of Boston Students for Justice in Palestine said they were told by police and venue staff to take down a sign reading “Will Ya #Feel The Bern 4 Palestine??!” According to an account posted on the group’s Facebook page, police threatened the activists with arrest if they did not leave.

Jeff Weaver, Sanders’ campaign manager, told the Washington Post on Oct. 5 that the instructions to take down the sign came from a “rogue” low-level campaign employee. “That person has been excluded from working on any of our future events,” Weaver said. He also said that the campaign called and apologized to the student group.
