US Senate Majority leader Chuck Schumer said at the March for Israel rally in Washington DC: "When Hamas says 'from the river to the sea,' they mean that all of present-day Israel should be a Jewish-free land. In fact, Hamas has says that what they did to the Jewish communities near the Gaza border, they should do to all Israelis."

"Never will we forget the evil of Hamas."

He led a chant of "never again."
