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.

Zohran Mamdani, the Democratic nominee for mayor of New York City, has been targeted by the president and other Republicans since his success in the primary.

New York City mayoral candidate Zohran Mamdani responded to President Donald Trump's threats of arrest, saying it's "an attack on democracy."
