Far from public view, the toll of the Donald Trump administration’s crackdown on immigration is unfolding in overcrowded detention facilities across the country.

Some immigrants have gone a week or more without showers. Others sleep pressed tightly together on bare floors. Medicine for diabetes, high blood pressure and other chronic health problems are often going unprovided. In New York and Los Angeles, people have been held for days in cramped rooms designed for brief processing, not prolonged confinement, and their lawyers and family members have remained in the dark about their whereabouts.

The nation’s immigration detention system is buckling under the weight of record numbers as the Trump administration intensifies its enforcement agenda with raids on workplaces and arrests at immigration courts. More than 56,000 immigrants were in government custody on June 15, exceeding the current capacity of 41,000.

“These are the worst conditions I have seen in my 20-year career,” said Paul Chavez, litigation and advocacy director at Americans for Immigrant Justice in Florida, which represents detainees. “Conditions were never great, but this is horrendous.”

At least 10 immigrants have died in ICE custody in the six months since Jan. 1, including two at a facility in Miami, the Krome detention center, where detainees this month formed a human “SOS” sign in the yard. At least two of the deaths were suicides, in Arizona and Georgia. (An average of about seven deaths a year occurred in ICE custody during the four years of Joe Biden’s administration.)

Immigration detentions have soared since late May, when Stephen Miller, the White House aide overseeing immigration policy, set a goal of 3,000 arrests per day.

To accommodate the swelling numbers, the administration has expanded contracts with prison operators and pushed for a substantial funding increase to secure additional capacity. The House version of the budget reconciliation bill proposes $45 billion for immigration detention, more than 10 times the current budget.

Many immigrants already have outstanding deportation orders, and others agree to voluntarily leave the country. In those cases, ICE officials are able to swiftly put them on planes or buses out of the country. But many others are entitled to court hearings, which take time, and ICE is either releasing those detainees on bond, which also requires a court hearing, or holding them in custody.

The Department of Homeland Security, which oversees ICE, categorically denied all claims of overcrowding and poor conditions at its facilities. A spokesperson, Tricia McLaughlin, said in a statement that all detainees “are provided with proper meals, medical treatment, and have opportunities to communicate with their family members and lawyers.”

McLaughlin added that Kristi Noem, the homeland security secretary, had called on states and local government to help with beds and detention space, and she noted that multiple court rulings have led to delays in deporting immigrants.

“Despite a historic number of injunctions, DHS is working rapidly overtime to remove these aliens from detention centers to their final destination — home,” McLaughlin said.

But interviews with more than two dozen former detainees, lawyers, family members and lawmakers suggest that conditions in facilities across the country have become unsanitary and intolerable.
