Police arrested more than a dozen New York state and city elected officials Thursday at 26 Federal Plaza, the Manhattan immigration court and an Immigration and Customs Enforcement (ICE) field office, many as they pressed to gain access to the building’s 10th-floor lockup, where recent court rulings—including a temporary restraining order—directed ICE not to cram immigrants into overcrowded, unsanitary conditions.

The lawmakers and other officials, arrested around 3:45 pm local time, say they were “attempting to conduct oversight” following claims that people appearing for court hearings were being confined for hours or days without proper food, medical care, or contact with attorneys.

A spokesperson for New York City comptroller Brad Lander’s office told WIRED by phone that Lander and 10 other elected officials were denied access and then arrested while “engaged in an action on the 10th floor of 26 Federal Plaza, where ICE inhumanely detains thousands of immigrant New Yorkers.” Lander was previously arrested at the same facility in June while accompanying a migrant man whom ICE targeted with arrest.

A joint press release issued by New York officials in the aftermath lists the electeds among those arrested:

• NYC comptroller Brad Lander
• State senator Julia Salazar
• State senator Jabari Brisport
• State senator Gustavo Rivera
• Assembly member Robert Carroll
• Assembly member Emily Gallagher
• Assembly member Jessica Gonzalez-Rojas
• Assembly member Marcela Mitaynes
• Assembly member Claire Valdez
• Assembly member Tony Simone
• Assembly member Steven Raga
• Public advocate Jumaane Williams
• Assembly member Phara Souffrant-Forrest
• Council member Sandy Nurse
• Council member Tiffany Caban

At least some officials, according to Lander’s office, had been released at the time of writing. The final four on the list were arrested outside the facility, reportedly by the New York City Police Department. Dozens of New Yorkers who had gathered, holding signs and chanting “ICE out of NY,” were also arrested, officials said. A follow-up demonstration was planned for 6 pm ET at Foley Square, a longtime rallying point for immigrant rights protests in the heart of Manhattan’s Civic Center neighborhood.

Neither the Department of Homeland Security nor ICE immediately responded to a request for comment. Reached by phone, a New York Police Department spokesperson declined to comment because “the incident is ongoing.”

Under federal law, members of Congress have explicit authority to inspect immigration detention facilities, including conducting unannounced visits. State and city lawmakers don’t have that authority and must rely on DHS or ICE to approve such requests. The Trump administration has instituted new policies, such as mandating advance notice and designating certain field offices and short-term sites off-limits, that have blocked or delayed congressional oversight visits in recent months.

Federal judges and civil rights groups have zeroed in on the conditions inside 26 Federal Plaza. This summer, a federal court issued a preliminary injunction against the government after allegations surfaced that the facility’s detainees were being crammed into severely overcrowded rooms and made to sleep on bare floors and were denied food, hygiene, and confidential access to their lawyers.

The problems echo a broader pattern across the US, where watchdogs and courts have flagged overcrowding, poor sanitation, and blocked access to counsel in ICE facilities from Arizona to Louisiana.

Advocates say some of the most jarring overcrowding is happening on 26 Federal Plaza’s 10th floor, where detainees have estimated that between 70 and 90 people have been crammed into rooms measuring roughly 215 square feet. That would leave each person with roughly the space of a doormat—less room than a folded bath towel—in an area no bigger than a studio apartment kitchen.

The arrests came as part of a coordinated action by progressive Democrats, timed to amplify demands for Albany to reconvene and pass the New York for All Act. The bill would bar state and local agencies, including police and sheriffs, from sharing information or resources with ICE, aiming to stop what lawmakers describe as abductions of immigrants at court hearings and check-ins. Along with New York City Council’s proposed Trust Act—which would let people sue if city agencies unlawfully cooperate with ICE—the legislation is essential, Democrats say, to defend due process and prevent local governments from becoming de facto extensions of ICE.

“The criminalization, demonization, and state-sponsored violence against immigrants in this country has reached a fever pitch under this administration. All of us, and especially elected leaders, must do more to protect New Yorkers, regardless of when they arrived,” Assembly member Emily Gallagher, a Democrat who represents parts of Brooklyn, said in a statement.

Many elected officials have been arrested while protesting the Trump administration’s immigration enforcement tactics. Among others, in June, Senator Alex Padilla of California was handcuffed after challenging Homeland Security secretary Kristi Noem at a Los Angeles press conference, and in May, Newark mayor Ras Baraka was arrested outside a federal detention center during an attempted oversight visit.

In a statement, Yasmine Farhang, executive director of the Immigrant Defense Project, applauded the lawmakers’ actions Thursday, accusing the US government of “egregious abuses of power,” and imploring New York governor Kathy Hochul to use her clemency powers to shield migrants dealing with overlapping punishments from the courts and immigration authorities.

“New York leaders cannot let this cruelty go unchecked,” she said. “The moment to act is NOW.”
