A Texas Republican congressman has introduced a bill targeting immigrants who advocate for or have ties to socialist, Marxist, or Islamic fundamentalist movements, naming it directly after New York City's Democratic mayor.
Rep. Chip Roy (TX-21) officially introduced the Measures Against Marxism's Dangerous Adherents and Noxious Islamists (MAMDANI) Act of 2026 on 20 April, seeking sweeping amendments to the Immigration and Nationality Act. The legislation would make any non-citizen affiliated with or advocating for socialist, communist, Chinese communist, Marxist, or Islamic fundamentalist parties or doctrines inadmissible to the United States, deportable if already resident, and ineligible for naturalisation.
