"As Israel continues to righteously fight to defend itself from barbaric terrorists, the most powerful Democrat in Congress knifed the Jewish state in the back," a RJC statement said — deriding the Schumer speech as having "demanded that Israel's democratically-elected government be evicted from power and replaced by one more to his liking."

"Sen. Schumer crossed a real red line," the statement said. "It is outrageous and unacceptable to meddle in Israel's domestic politics by demanding that a democratic ally hold elections on our timetable, particularly when the Jewish state is fighting for its very survival."

The lashing noted that Schumer "has frequently described himself as the so-called 'Shomer', or guardian, of the Jewish people, but that his remarks Thursday were "a 'Shanda', a disgrace."
