The Big Apple's new mayor Zohran Mamdani has created history...becoming the first Indian-origin Muslim socialist the take up the city's top post. A polarising figure in American politics, the 34-year-old's meteoric rise has been anything but smooth. Among his fiercest critics has been President Trump...calling him a Commie Lunatic, a Jew Hater to threatening to hold back federal funds from New York. Mamdani has made it clear...he's Trump's "worst nightmare".
