Watch the explosive showdown between President Trump and NYC mayoral candidate Zohran Mamdani in Des Moines on July 4th. Trump labeled Mamdani a “communist threat” and warned of anarchy and the collapse of American values.

President Donald Trump on Sunday issued a warning for New York city mayoral candidate Zohran Mamdani, the presumptive Democratic nominee who defeated former Governor Andrew Cuomo in last week's primary and sent shockwaves throughout the national political establishment.

Zohran Mamdani clinched victory Tuesday in the Democratic primary for New York City mayor and quickly drew more attacks and threats of arrest from President Donald Trump, a Queens native likely to be a central figure in one of this year’s most important contests.
