A new wave of bomb threats against Jewish community centers swept the U.S. Tuesday, with reported threats against JCCs in New York, Wisconsin, Illinois and Florida. On Tuesday, a letter signed by all 100 U.S. senators urged Attorney General Jeff Sessions, FBI Director James Comey and Homeland Security Secretary John Kelly to take action. New York City Mayor Bill de Blasio also spoke out against the attacks Tuesday.

Mayor Bill de Blasio: “And we know that new threats are coming in, literally as of today, directed at other Jewish community institutions around the country. And this is a very troubling reality. This is a moment in time, a moment in history, where forces of hate have been unleashed.”
