Shockingly, CAIR along with the Stalinist ANSWER Coalition sponsored the protest.
Via Breitbart:
… One pro-Israel protestor showed up on the other side of the crowd, alone, with an Israel flag in one hand and an an American flag in the other.
The pro-Palestine protestors grew belligerent — shouting slogans at him, giving him the middle finger. One tried to light his Israeli flag on fire.
But Manny Vega, an undeterred retired U.S. Marine and Iraq War veteran, spoke to Breitbart News about the incident.
“What brought me out here is this sort of anti-Israel atmosphere that this administration is holding over the United States,” Vega told Breitbart News. “I want to show the Israeli people there are American people in our nation that support the state of Israel… And that is why am standing here with an American flag on my right hand, and Israeli flag on my left hand, in a show of solidarity with the Israeli people.”
