Homeland Security Secretary Kristi Noem said New York City Mayor-elect Zohran Mamdani (D) may have “violated the Constitution” by informing migrants of their rights if approached by immigration officers.

“We’re certainly going after and looking into all of that with coordination of the Department of Justice,” she said during an appearance on Fox News’s “Hannity,” adding that Mamdani “could be violating the Constitution by giving advice on how to evade law enforcement and how to get away with breaking the law.”

Mamdani on Monday said that as mayor, he would “protect the rights” of the roughly 3 million migrants in New York City in a “know your rights” video posted on the social platform X.

In the video, Mamdani is seen reminding viewers that U.S. Immigration and Customs Enforcement (ICE) agents can be refused entry into a home if they do not have a warrant but also said that people may not impede an investigation.
