Zohran Mamdani made history Tuesday night, becoming the first Muslim mayor of New York City -- and his first order of business was going after his nemesis, President Trump! The democratic socialist breezed to victory over his closest opponent, Andrew Cuomo, in the NYC mayoral race -- then took the stage at the Paramount Theater in Brooklyn, delivering a 20-minute speech celebrating his big win, and vowed to stop Trump once and for all. Standing at a podium flanked by his wife, Rama Duwaji, Mamdani told his huge crowd of supporters, "If any city can show a nation how to stop Donald Trump, it is the city that gave rise to him." Trump, of course, was born and raised in Queens -- and spent much of his life building his real estate empire in Manhattan. But Mamdani wasn't done yet ... the mayor-elect then gave Trump a direct order, stating, "Donald Trump, since I know you're watching, I have four words for you: turn the volume up!" Trump later hopped on Truth Social to fire back at Mamdani with a one-line response ... "AND SO IT BEGINS!" As everyone knows, DT is no fan of Mamdani -- their political views couldn't be father apart -- and he's repeatedly labeled the new mayor a communist.
