At the height of the debate over Israel’s possible annexation of the West Bank last summer, J Street, the liberal pro-Israel group, was urging followers on social media to write to Senators opposing the move. Elan Carr, the State Department’s envoy to combat antisemitism, jumped in to take exception to J Street’s use in a Tweet of a photo of then-President Donald Trump and Israeli Prime Minister Benjamin Netanyahu speaking at the White House as Jared Kushner and two other Jewish advisers looked on. “How dare @jstreetdotorg use this picture in this context,” Carr said in a message from his government Twitter account. “Their imagery uses #Antisemitism and crude anti-Semitic conspiracy theories to advance their agenda.”
