Z ohran Mamdani, the Democratic nominee for New York City mayor, pointedly explained why he thinks President Donald Trump has levied attacks on his citizenship and threatened to arrest him in recent days. Trump simply needs a distraction, Mamdani argued in a press conference with New York City labor leaders on Wednesday.

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.

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.
