Rep. Chip Roy introduced the 'Mamdani Act,' legislation that would make noncitizens who advocate for or are affiliated with socialist, communist, Marxist, or Islamic fundamentalist movements deportable and ineligible for entry or naturalization, while stripping courts of power to review deportation decisions. The bill is named after NYC Mayor Zohran Mamdani, a democratic socialist, and would apply the same restrictions to both authoritarian communism and democratic socialism without legal distinction. Democratic socialists like Bernie Sanders and AOC distinguish themselves from Soviet-style regimes by emphasizing democratic elections rather than revolution, but the bill does not make this distinction in its prohibitions. This is a real proposal from 2026, covered by Newsweek and other outlets, though it remains unclear whether the bill has advanced beyond introduction or gained co-sponsors.
