New York's mayor, Zohran Mamdani, exalted the city's legacy of immigrants on Friday in a historically laden, ideological counterpoint to a US semiquincentennial address that was expected later in the day from Donald Trump " who has sought to deport immigrants en masse throughout his second presidency. Speaking from behind a desk at New York's city hall that belonged to the US's first president, George Washington, and which itself is a century older than the Resolute desk in the White House, Mamdani was surrounded by naturalized citizens like himself as he listed the waves of immigrants who shaped the city.
