On the eve of New York City's mayoral election, US President Donald Trump has warned that federal funds could be slashed if Democratic frontrunner Zohran Mamdani wins. Writing on Truth Social, Trump called the 34-year-old candidate a 'communist' and said his victory would mean 'zero chance of success, or even survival' for his 'beloved first home'. Mamdani, a progressive Democrat, is leading in the polls and could become the city's first Muslim mayor.
