[So the dual-citizenship-with-Israel guy tries to get the US to pay for security for US mosques, right?]
Not sure where you’re getting the dual citizen stuff. Schumer is Jewish and eligible for Israeli citizenship just as you’re eligible for citizenship in whatever European countries from which your ancestors hailed. But I’ve never heard that he had taken up Israeli citizenship, apart from a dubious source that basically listed the entire Jewish delegation of Congress as dual citizens of the US and Israel.
