House Republican Rep. Chip Roy, R-Texas, a prominent member of the House Freedom Caucus known for his strong conservative stance on immigration and cultural issues, has introduced legislation he calls the “Mamdani Act.”
The bill would expand U.S. immigration law to make non-citizens deportable, inadmissible, or subject to denaturalization based on ideological beliefs or affiliations.
Under the proposal, individuals linked to or supportive of socialist, communist, Marxist, or what Roy characterizes as Islamist extremist movements could be barred from entry or removed from the country.
The measure also seeks to deny admission and citizenship pathways to people deemed associated with those ideologies while creating new grounds for deportation of those already living in the United States.
Roy has framed the legislation as a national security and values-based measure aimed at excluding what he describes as “totalitarian” ideologies incompatible with American principles.
The proposal further reflects Roy’s broader political identity as one of the most outspoken hardliners in the House GOP, frequently pushing aggressive immigration restrictions and expanded enforcement powers.
