"We need to be strong in the Jewish community, and we need to be strong about standing up against discrimination of any kind," said Minnesota Vikings co-owner Mark Wilf. A virtual rally took place on Thursday to call out the violence and hate against the Jewish community.

Waves of threats against U.S. Jewish groups have been followed within hours by similar but smaller waves against Jewish organizations, mainly schools.
Threats were phoned in or emailed to JCCs in states including New York, Wisconsin, Illinois and Florida overnight and early on Tuesday.
The threats, all of which appeared to be hoaxes, were received in Alabama, Delaware, Florida, Indiana, Maryland, Michigan, New Jersey, New York, North Carolina, Pennsylvania and Virginia.
No one claimed responsibility for the calls on Wednesday nor nine days ago, and the Federal Bureau of Investigation (FBI) has not named any suspects nor described a likely motive.
