New York City Democratic Mayor Zohran Mamdani on Monday announced a joint lawsuit with other mayors against the Trump administration over a planned rule that would block green cards and visas to people using welfare programs.

“The new public charge rule seeks to push immigrant families away from the programs that have kept people fed and healthy for decades. New Yorkers will be afraid to see a doctor or ask for help they are legally entitled to,” Mamdani said, according to Politico.

The suit comes alongside a separate challenge from New York Attorney General Letitia James.

Among the cities joining New York City in the challenge are Chicago and San Francisco.

The proposal is one of several administrative efforts from Trump to curb legal immigration and lower the number of people receiving taxpayer dollars through social safety net programs.
