One GOP Rep is introducing an immigration bill to deport a vast swathe of people, and he names it after the NYC mayor

Rep. Chip Roy (R-Texas) officially introduced a new immigration bill that targets migrants affiliated with specific political and religious ideologies, and he has explicitly named the legislation after a New York City politician. The bill, which is formally titled the Measures Against Marxism’s Dangerous Adherents and Noxious Islamists Act, uses the acronym MAMDANI Act, The Hill reported. This is a direct reference to New York City Mayor Zohran Mamdani (D), who is a democratic socialist and a naturalized U.S. citizen born in Uganda.

The proposed legislation is quite extensive in its scope, aiming to amend the existing Immigration and Nationality Act. If passed, it would grant the federal government the power to deport, denaturalize, or deny entry and citizenship to any migrant identified as a member of a socialist, communist, Chinese communist, or Islamic fundamentalist party.

The bill doesn’t just stop at formal party membership, however. It also targets individuals who advocate for these ideologies. The definition of advocacy within the bill is incredibly broad, as it covers writing, distributing, circulating, printing, displaying, possessing, or publishing any written, electronic, or printed matter that supports these belief systems.

It’s a massive shift in how we handle immigration law, and the implications for personal expression and association are significant

According to the text of the bill, anyone who falls under these categories could face severe consequences regarding their status in the country. There is one narrow exception included in the bill, which states that migrants who can prove their advocacy for these ideologies occurred before they reached the age of 14 will be exempt from these specific restrictions.

When it comes to the classification of an Islamic fundamentalist party, the bill specifically names several organizations. These include the Muslim Brotherhood, the Islamic State, the Al-Nour Party, Hamas, Hezbollah, Boko Haram, and Al-Shabaab.

The legislation also includes a provision that makes any determinations regarding inadmissibility, deportability, naturalization, or denaturalization final, meaning they would not be subject to any review by a court.

In a press release regarding the introduction of the act, Roy explained his reasoning for the bill. He asked why the U.S. continues “to import people who hate us?” in reference to those who support the ideologies targeted by the legislation. He went on to argue that the immigration system has been used to harm the competitiveness of American workers.

“Not just for the last six years, but for the last 60 years, our immigration system has been cynically used to disadvantage American workers’ competitiveness in favor of mass-importing the third world,” said the Texas Republican, who is currently running for state Attorney General. “This has not just led to higher crime and lower wages, but also the promulgation of hostile ideologies fundamentally opposed to American values.”

Roy further stated that the bill is designed to combat what he calls the Red-Green Alliance. “By targeting the Red-Green Alliance, this legislation deploys new tools to fight back against the Marxist and Islamist advance that has devastated Europe and has now arrived on our doorstep, especially in my home state of Texas,” he added. A one-page summary provided by his office suggests that the presence of individuals like Zohran Mamdani demonstrates how the current immigration system enables the mass importation of those he describes as Marxists and Islamists.

This isn’t the first time Roy has focused on these issues. In October 2025, he introduced the Preserving a Sharia-Free America Act, which sought to prevent foreign nationals who observe Sharia law from entering or remaining in the U.S.

During his promotion of that previous bill, Roy expressed his view that Sharia law is incompatible with what he described as “our Judeo-Christian-founded Western civilization laws.” He has also previously raised concerns about the growth of religious enclaves and the potential for what he terms parallel legal systems in the United States, citing developments in places like Texas and New York.

The naming of this new act is clearly a pointed move. By using the MAMDANI acronym, Roy is directly attacking the New York politician, whom he has previously described as an “Islamist Marxist.” Roy has also previously called for the Department of Homeland Security and the Department of Justice to scrutinize Mamdani’s background, particularly in relation to his associations and the naturalization process.
