Congress Sues ICE Over Blocked Detention Facility Access

Twelve Democratic members of the U.S. House of Representatives sued Immigration and Customs Enforcement and the Department of Homeland Security in July 2025 after the Trump administration blocked them from conducting unannounced oversight visits to federal immigration detention facilities. The administration imposed a policy requiring seven days’ advance notice before any congressional visit, a direct conflict with a 2019 federal law prohibiting DHS from using appropriated funds to prevent members of Congress from entering facilities where immigrants are detained.

The case, Neguse et al. v. U.S. Immigration and Customs Enforcement et al., Case No. 1:25-cv-02463, is before U.S. District Judge Jia M. Cobb in the U.S. District Court for the District of Columbia. Federal courts have sided with the lawmakers at every turn. A December 2025 stay, a February 2026 temporary restraining order, and a March 2026 preliminary injunction have all blocked the seven-day notice policy. On May 8, 2026, the U.S. Court of Appeals for the D.C. Circuit unanimously denied the administration’s request for a stay pending appeal, leaving the injunction in place.

Lawsuit Timeline and Updates

June to July 2025 — DHS Blocks Congressional Access, Lawsuit Filed

Under Section 527 of the DHS Appropriations Act, a federal law first enacted in 2019, no DHS funds may be used to prevent members of Congress or their staff from entering, for purposes of oversight, any facility operated by or for DHS used to detain immigrants. The law requires no prior notice from lawmakers, though it permits DHS to require congressional staff to give at least 24 hours’ notice.

In June 2025, ICE released updated guidance declaring that ICE field offices — which the agency was increasingly using to house detainees as bed space at formal detention centers ran out — were “not detention facilities” and therefore fell outside Section 527’s reach. ICE also unilaterally imposed a requirement of at least 72 hours’ advance notice for oversight visits, far exceeding what the statute allowed for staff. When Democratic lawmakers attempted to conduct oversight visits to ICE facilities in June and July 2025, they were denied entry.

On July 30, 2025, twelve Democratic House members filed the lawsuit in the U.S. District Court for the District of Columbia. The plaintiffs were represented by Democracy Forward Foundation and American Oversight. They included Assistant Democratic Leader Joe Neguse of Colorado, Congressional Hispanic Caucus Chair Adriano Espaillat, Judiciary Committee Ranking Member Jamie Raskin, Homeland Security Committee Ranking Member Bennie Thompson, House Oversight Committee Ranking Member Robert Garcia, Border Security Subcommittee Ranking Member J. Luis Correa, Jason Crow, Veronica Escobar, Dan Goldman, Jimmy Gomez, and Raul Ruiz.

August 2025 — DHS Escalates to Seven-Day Notice Requirement

The administration did not soften the policy after the lawsuit was filed. Instead, DHS Secretary Kristi Noem escalated it, imposing a new requirement that members of Congress provide at least seven days’ advance notice before any oversight visit to an ICE detention facility. Noem characterized recent congressional visits as “circus-like publicity stunts” that created a “chaotic environment” at facilities.

On August 8, 2025, the plaintiffs moved to stay the new seven-day policy under the Administrative Procedure Act, or alternatively for a preliminary injunction. Briefing proceeded through September, with the government arguing the policy was necessary for the safety of members of Congress, congressional staff, detainees, and ICE personnel. The government also maintained that ICE field offices being used for detention were not covered by Section 527. The hearing was originally scheduled for September 25 but was paused due to a federal government shutdown.

December 17, 2025 — Judge Cobb Stays the Seven-Day Notice Policy

After briefing resumed following the end of the shutdown, Judge Jia Cobb issued a stay of the seven-day notice policy on December 17, 2025. The stay was granted under Section 705 of the Administrative Procedure Act, which allows courts to preserve the status quo during litigation when an agency action is likely unlawful.

Judge Cobb’s analysis was direct. Section 527 prohibited DHS from using appropriated funds to prevent congressional access to detention facilities. The seven-day notice requirement had exactly that effect: it prevented timely, real-time oversight of the facilities plaintiffs needed to inspect. The information members sought — about overcrowding, shackling, denial of medical care, lack of access to counsel, and other conditions — was time-sensitive. A seven-day delay allowed ICE to prepare for visits and potentially conceal conditions the law was designed to expose. The court stayed the policy “[u]nless and until Defendants show that no Section 527 funds are being used for these purposes.”

January 8, 2026 — Noem Secretly Reinstates Identical Policy Under New Funding Claim

Rather than comply with Judge Cobb’s order, Secretary Noem quietly signed a new memorandum on January 8, 2026, reinstating the seven-day notice requirement. The memo was not shared with plaintiffs or the court. Noem argued the new policy was exempt from the December stay because ICE was now enforcing it using funding appropriated through Trump’s One Big Beautiful Bill Act, rather than through the standard DHS appropriations bill. Since Section 527 applied to DHS appropriations funds, Noem claimed the new law’s funding source placed the policy outside the court’s order.

The memo only came to light after three Minnesota Democrats — Reps. Ilhan Omar, Angie Craig, and Kelly Morrison — were denied entry to an ICE facility outside Minneapolis on January 10, 2026, despite arriving with a copy of Judge Cobb’s court order in hand. The denials occurred in the immediate aftermath of an ICE officer fatally shooting Minneapolis resident Renee Nicole Good during an immigration enforcement operation — an incident that had already prompted intense public and congressional scrutiny of ICE’s operations in the city.

January 12, 2026 — Lawmakers File Emergency Motion; Court Denies on Procedural Grounds

On January 12, 2026, the Democratic lawmakers returned to court, filing a motion for an order to show cause demanding that DHS explain how the duplicate notice policy complied with Judge Cobb’s previous order. The motion also requested an emergency hearing. Judge Cobb held argument on January 14 but denied the motion on January 19 on procedural grounds, holding that challenging the January 8 memo required filing an amended complaint or supplemental brief rather than a show-cause motion.

The denial was not a ruling on the merits. Judge Cobb made clear that the proper vehicle for challenging the new policy remained available, and the plaintiffs promptly used it.

January 26, 2026 — Amended Complaint Filed; TRO Sought; Rep. Morrison Joins

On January 26, 2026, the plaintiffs filed an amended complaint adding Rep. Kelly Morrison as a named plaintiff after she was denied access to the Bishop Henry Whipple Federal Building in Minnesota. The amended filing challenged the January 8 Noem memo directly and renewed the request for emergency relief in the form of a temporary restraining order. The administration opposed the TRO, arguing the OBBBA funding claim rendered the new policy lawful and outside the scope of the prior court order.

February 2, 2026 — Judge Cobb Grants Emergency TRO, Restores Unannounced Access

Judge Cobb granted the TRO on February 2, 2026, ordering DHS and ICE to immediately restore the 13 plaintiff members’ ability to enter detention facilities without advance notice, speak with detainees, and investigate conditions in real time. The court found the plaintiffs were likely to succeed on the merits — specifically, that Section 527-restricted funds were being used to implement the January 8 Noem memo, rendering the administration’s OBBBA funding argument unpersuasive at this stage.

The court also reaffirmed its earlier irreparable harm finding. “If anything, the strength of that finding has become greater over the intervening weeks,” Cobb wrote, “given that ICE’s enforcement and detention practices have become the focus of intense national and congressional interest.” ICE responded through a spokesperson: “We strongly disagree with this ruling and will keep fighting for the safety of everyone involved.”

March 2, 2026 — Preliminary Injunction Issued, Extending to All Members of Congress

On March 2, 2026, Judge Cobb converted the TRO into a preliminary injunction and expanded its scope beyond the 13 named plaintiffs. The preliminary injunction restored unannounced oversight access for all members of Congress, not just the lawsuit’s named plaintiffs. The court found that the January 8 Noem memo violated Section 527 and was not insulated from that law by the OBBBA funding argument. ICE and DHS filed notice of appeal to the D.C. Circuit.

May 8, 2026 — D.C. Circuit Unanimously Denies Stay, Injunction Holds

The D.C. Circuit Court of Appeals, in a unanimous ruling issued May 8, 2026, denied the administration’s request for a stay of Judge Cobb’s preliminary injunction pending the appeal. Judge Rao issued a concurring statement noting that DHS had failed to demonstrate irreparable harm from being required to allow congressional oversight visits without advance notice. The preliminary injunction remains fully in force. Members of Congress retain the right to conduct unannounced visits to ICE detention facilities while the underlying appeal continues.

What the Lawsuit Alleges

The lawsuit rests on a straightforward statutory argument. Section 527 of the DHS Appropriations Act prohibits DHS from using appropriated funds to prevent members of Congress — or their employees — from entering “any facility operated by or for the Department of Homeland Security used to detain or otherwise house aliens” when those members are conducting oversight. The statute explicitly requires no prior notice from lawmakers, though DHS may require congressional staff to provide at least 24 hours’ notice.

The seven-day notice requirement directly violated this statutory prohibition. By requiring lawmakers to announce visits a week in advance, the policy functionally prevented the real-time, unannounced inspections that Section 527 was designed to protect. Plaintiffs argued that advance notice gave ICE time to prepare facilities, remove detainees from view, or otherwise conceal the conditions that oversight was meant to expose.

The plaintiffs also raised APA ultra vires claims, arguing that even absent a specific statutory violation, the executive branch cannot act in a manner entirely outside any authority Congress has granted. The Administration Procedure Act’s Section 705 allows courts to stay unlawful agency action during litigation. Judge Cobb applied that provision in December 2025.

The Administration’s Defense

DHS and ICE advanced three main arguments. First, on safety: Noem’s memo argued that unannounced congressional visits created unpredictable security situations at facilities housing large populations of detainees. ICE contended that seven days’ notice was needed to ensure adequate protection for lawmakers, staff, detainees, and ICE personnel. Judge Cobb rejected this, finding the government had “not cited any concrete examples of safety issues posed by congressional visits without advanced notice.”

Second, on scope: ICE argued that field offices were not “detention facilities” under Section 527 and therefore fell outside the oversight law’s reach. This argument collapsed as evidence showed ICE was using those same field offices to house immigrants for days at a time — precisely the circumstance Section 527 addressed.

Third, on funding: after Judge Cobb’s December 2025 stay, Noem’s January 8 memo argued the policy was now operating on OBBBA funds not subject to Section 527 restrictions. Courts found the administration had not demonstrated that no Section 527 funds were supporting the policy’s implementation and enforcement. The D.C. Circuit’s May 2026 denial of a stay while the appeal proceeds confirmed that this argument had not overcome the preliminary injunction standard.

Conditions Inside the Facilities

The stakes of oversight access are not abstract. The lawsuit and related congressional reports describe conditions at ICE detention facilities that lawmakers say require independent real-time verification. Reported conditions include overcrowding beyond facility capacity, the use of shackles on detainees during routine movement, denial of medical care including for acute conditions, lack of meaningful access to legal counsel, and inadequate sanitation.

Plaintiffs note that 2025 marked the deadliest year for people in ICE custody in more than two decades, coinciding with record-high detention numbers as the Trump administration implemented its mass deportation agenda. In that context, the ability to conduct unannounced visits is not a procedural nicety — it is the mechanism that makes oversight meaningful rather than performative.

The Minnesota situation illustrated this directly. After an ICE officer fatally shot Renee Nicole Good, a U.S. citizen, during enforcement operations in Minneapolis, three members of Congress sought to visit a nearby facility to assess conditions. They were turned away under the Noem memo, despite carrying a valid federal court order. The episode prompted Rep. Omar’s statement: “Members of Congress have a legal right and constitutional responsibility to conduct oversight where people are being detained. The public deserves to know what is taking place in ICE facilities.”

The Section 527 Funding Battle

The administration’s OBBBA funding argument deserves closer examination because it represents the administration’s most creative attempt to insulate enforcement actions from statutory and judicial oversight. The One Big Beautiful Bill Act, passed as part of Republican fiscal legislation, appropriated funds to ICE and DHS outside the standard annual appropriations cycle. Noem’s legal theory was that these funds were not DHS “appropriated” funds in the traditional sense and therefore were not subject to the Section 527 rider that Congress had attached to annual DHS appropriations bills.

Courts found this argument unpersuasive for a simple reason: the administration could not demonstrate that no Section 527-restricted funds were touching the implementation of the notice policy. ICE operations are funded through multiple streams simultaneously, and detention operations during the period in question drew on both OBBBA and traditional appropriations. Until the administration can affirmatively prove complete funding separation, the Section 527 prohibition applies.

What matters here is the structural implication. If the administration’s theory were accepted, Congress could be stripped of any oversight mechanism simply by routing enforcement activities through a different appropriations vehicle. The rider that Congress wrote precisely to protect its oversight rights would become meaningless — circumventable at the executive branch’s discretion simply by relabeling the source of funds. No federal court has accepted that reading.

Separation of Powers at Stake

The lawsuit is fundamentally a separation-of-powers case. Congress created ICE through legislation, funds it through appropriations, and has the constitutional responsibility to conduct oversight of how executive agencies spend taxpayer money and comply with federal law. The oversight mechanism Congress chose to protect in Section 527 was not incidental — it was deliberate, specific, and enacted after prior incidents in which access to detention facilities was restricted.

The Trump administration’s position — that the executive branch can define the terms of congressional oversight of executive branch facilities — inverts this relationship. Courts have consistently rejected the argument that the president’s plenary authority over executive agencies extends to blocking Congress from seeing what those agencies are doing inside facilities Congress funds. As Judge Cobb wrote, the notice policy “imposes irreparable harm upon the Plaintiffs in denying them the ability to carry out timely oversight.” Irreparable harm from being prevented from doing a constitutionally required job is not a close call.

The parallel to the DOGE transparency FOIA lawsuit is clear: in both cases, the administration resisted disclosure of how executive power is being exercised, and in both cases federal courts pushed back. Congressional oversight of ICE detention, like FOIA access to DOGE records, is not a partisan request — it is a structural requirement of constitutional government. For broader context on how separation-of-powers disputes are playing out across the federal judiciary in 2026, see also the Trump White House ballroom lawsuit, where courts similarly held that presidential authority has limits even over property the president occupies.

What This Lawsuit Teaches Consumers

The ICE facility notice requirement lawsuit is not about immigration policy. Courts in this case have not been asked to evaluate whether the Trump administration’s detention and enforcement practices are good policy. They have been asked a narrower question: can the executive branch use federal funds to prevent Congress from seeing what the executive branch is doing? Federal courts have answered that question three times in this case, and the answer has been the same each time: no.

What this case reveals is the practical importance of oversight mechanisms that most people never think about. Section 527 is a technical provision in a DHS spending bill. It was not on the front page when Congress enacted it. But without it — or more precisely, without courts willing to enforce it — the only people permitted to assess conditions inside federal detention facilities would be the agency operating them. That is not oversight. That is self-reporting.

The administration’s playbook in this case has been to impose a restriction, get blocked by a court, reimpose a functionally identical restriction through a slightly different mechanism, get blocked again, and appeal. Each cycle delays accountability while the underlying conditions in facilities continue. The D.C. Circuit’s May 8, 2026 denial of a stay suggests courts are not going to allow that cycle to repeat indefinitely. The injunction holds. Members of Congress can walk in unannounced. And the appeal, when it is decided on the merits, will determine whether that access is permanent — or whether the administration gets another chance to find a new mechanism to block it.
