Z ohran Mamdani, the Democratic nominee for New York City mayor, hit back at President Donald Trump on Wednesday, accusing him of issuing deportation threats in retaliation for opposing federal immigration enforcement.

The president, who has a history of spewing sometimes vile insults at rivals, has in recent days escalated his attacks against the 33-year-old self-described democratic socialist. Trump has threatened to arrest Mamdani, to deport him and even to take over the country’s largest city if he wins the general election in November.
