Swastikas were discovered spray-painted on the Magen David Yeshiva in Brooklyn during the New York City mayoral election night, prompting widespread condemnation from city and state leaders. The incident was one of several acts of vandalism targeting Jewish sites that evening, highlighting a surge in antisemitic hate crimes across the city. Newly elected mayor Zohran Mamdani and outgoing mayor Eric Adams both denounced the attack, while Jewish organizations expressed deep concern over the rise in antisemitism. The Anti-Defamation League announced a new initiative to monitor Mamdani's administration, citing his controversial past statements, as the mayor-elect pledged to protect and support Jewish communities in New York City.
