WASHINGTON — Twelve House Democrats who last year sued the Trump administration over a policy limiting congressional oversight of immigrant detention facilities returned to federal court Monday to challenge a second, new policy imposing further limits on such unannounced visits.

In December, those members of Congress won their lawsuit challenging a Department of Homeland Security policy from June that required a week’s notice from lawmakers before an oversight visit. Now they’re accusing Homeland Security of having “secretly reimposed” the requirement last week.

In a Jan. 8 memorandum, Homeland Security Secretary Kristi Noem wrote that “Facility visit requests must be made a minimum of seven (7) calendar days in advance. Any requests to shorten that time must be approved by me.”

The lawmakers who challenged the policies are led by Rep. Joe Neguse (D-Colo.) and include five members from California: Reps. Robert Garcia (D-Long Beach), Lou Correa (D-Santa Ana), Jimmy Gomez (D-Los Angeles), Raul Ruiz (D-Indio) and Norma Torres (D-Pomona).

Last summer, as immigration raids spread through Los Angeles and other parts of Southern California, many Democrats including those named in the lawsuit were denied entry to local detention facilities. Before then, unannounced inspections had been a common, long-standing practice under congressional oversight powers.

“The duplicate notice policy is a transparent attempt by DHS to again subvert Congress’s will…and this Court’s stay of DHS’s oversight visit policy,” the plaintiffs wrote in a federal court motion Monday requesting an emergency hearing.

On Saturday, three days after Renee Nicole Good was shot and killed by an Immigration and Customs Enforcement agent, three members of Congress from Minnesota attempted to conduct an oversight visit of an ICE facility near Minneapolis. They were denied access.

Afterward, lawyers for Homeland Security notified the lawmakers and the court of the new policy, according to the court filing.

In a joint statement, the plaintiffs wrote that “rather than complying with the law, the Department of Homeland Security is attempting to get around this order by re-imposing the same unlawful policy.”

“This is unacceptable,” they said. “Oversight is a core responsibility of Members of Congress, and a constitutional duty we do not take lightly. It is not something the executive branch can turn on or off at will.”

Congress has stipulated in yearly appropriations packages since 2020 that funds may not be used to prevent a member of Congress “from entering, for the purpose of conducting oversight, any facility operated by or for the Department of Homeland Security used to detain or otherwise house aliens.”

That language formed the basis of the decision last month by U.S. District Court Judge Jia Cobb in Washington, who found that lawmakers cannot be denied entry for visits “unless and until” the government could show that no appropriations money was being used to operate detention facilities.

In her policy memorandum, Noem wrote that funds from the One Big Beautiful Bill Act, which supplied roughly $170 billion toward immigration and border enforcement, are not subject to the limitations of the yearly appropriations law.

“ICE must ensure that this policy is implemented and enforced exclusively with money appropriated by OBBBA,” Noem said.

Noem said the new policy is justified because unannounced visits pull ICE officers away from their normal duties. “Moreover, there is an increasing trend of replacing legitimate oversight activities with circus-like publicity stunts, all of which creates a chaotic environment with heightened emotions,” she wrote.

The lawmakers, in the court filing, argued it’s clear that the new policy violates the law.

“It is practically impossible that the development, promulgation, communication, and implementation of this policy has been, and will be, accomplished — as required — without using a single dollar of annually appropriated funds,” they wrote.

Rep. Ro Khanna, D-Calif., called for the arrest and prosecution of the ICE agent who fatally shot Renee Good in a residential neighborhood of Minneapolis, Minnesota on Jan. 7.

Khanna also urged Congress to back his legislation with Rep. Jasmine Crockett, D-Texas, to require ICE agents to wear body cameras, display visible identification, stop wearing masks during operations and be subject to independent oversight.

In a post shared on X, the former Obama administration official said: “I am calling for the arrest and prosecution of the ICE agent that shot and killed Renee Good.”

“I am also calling on Congress to support my bill with @JasmineForUS to force ICE agents to wear body cameras, not wear masks, have visible identification, and ensure ICE has independent oversight,” Khanna added.

An ICE agent shot and killed the 37-year-old Minneapolis woman during a federal enforcement operation in south Minneapolis. Federal officials have said agents were attempting to make arrests when the woman tried to use her vehicle as a weapon against officers, prompting an ICE agent to fire in self-defense.

Good’s death sparked widespread protests in Minneapolis and across the U.S. as demonstrators called for changes to federal immigration enforcement.

Local officials, including Minneapolis Mayor Jacob Frey and Minnesota Governor Tim Walz, criticized the federal account of the incident and rejected the claim that the officer acted in self-defense. Minnesota has since sued the Trump administration, claiming the immigration enforcement surge in the state is “unlawful” and “unprecedented.”

“What we are seeing right now is not normal immigration enforcement,” Frey said. “The scale is wildly disproportionate, and it has nothing to do with keeping people safe.”

The Trump administration pushed back sharply against the lawsuit, with the Department of Homeland Security (DHS) accusing Minnesota leaders of undermining public safety and obstructing federal law enforcement.

Federal officials, including DHS Secretary Kristi Noem, maintained that the agent fired in self-defense.

Noem critisized Democrats on Sunday amid an Illinois lawmaker’s push to impeach her following the deadly shooting.

“These law enforcement officers are trained to be in situations that are dangerous, and they rely on that training each and every day to make the right decisions,” Noem said during “Sunday Morning Futures.”
