Rep. Chip Roy (R-TX) introduced a bill in the House on Monday that would deport, denaturalize, and citizenship and entry to any immigrant who advocates for socialism or Marxism.

The bill, called the “Measures Against Marxism’s Dangerous Adherents and Noxious Islamists,” or MAMDANI, Act, is a reference to socialist New York City Mayor Zohran Mamdani, who is also a Ugandan immigrant.
