Military bases in both New Jersey and Indiana will soon be used by Homeland Security to house illegal immigrants, drawing a furious response from Democratic lawmakers.

Parts of Joint Base McGuire-Dix-Lakehurst in New Jersey and Camp Atterbury in Indiana will be repurposed and used as “temporary soft-sided holding facilities,” the Defense Department told Fox News Digital, citing a decision by Defense Secretary Pete Hegseth.

New Jersey Democrats blasted the decision, warning it would harm military readiness and urging Republicans to join them in helping reverse it. Both bases were previously used to house thousands of Afghan refugees following the U.S. withdrawal from Afghanistan in 2021.

It is unclear when either site will open and a decision will depend on operational requirements and coordination with Homeland Security, the Defense Department said. 

Joint Base McGuire-Dix-Lakehurst is a joint military base operated by U.S. Air Force, Army and Navy — the only tri-service base in the country. Spanning 42,00 acres, it’s home to 45,000 military and civilian personnel, making it one of the largest and most strategically important on the East Coast.

Camp Atterbury is an Army and Air National Guard base near Edinburgh that spans 34,000 acres and has been used for training brigades and hosting large-scale operations. 

Under the Trump administration, Homeland Security has been using detention facilities to house migrants while they await asylum hearings or deportation. 

The lawmakers said that Hegseth wrote to Conoway informing him of the decision. Hegseth wrote in the letter that the move would not negatively affect military training, operations, readiness, or any other military requirements, per NJ Spotlight News.

New Jersey is already home to Delaney Hall and the Elizabeth Detention Center which are being used as immigration detention facilities, although they are privately operated. Delaney Hall was the scene where Democrat Newark Mayor Ras Baraka was arrested and charged with trespassing in a clash with federal immigration officials in May. Rep. LaMonica McIver, D‑N.J., was later federally charged for allegedly interfering with federal officers during the same incident.

The news comes two weeks after President Donald Trump signed the Big Beautiful Bill into law, which allocated between $150 billion and $170 billion towards immigration enforcement over the next several years, $45 billion of which was carved out to expand immigration detention facilities. The funds are part of the Trump administration’s efforts to carry out the largest deportation operation in the nation’s history. 

Earlier this month, the Trump administration opened an immigration detention camp in Florida’s Everglades that is surrounded by alligators dubbed “Alligator Alcatraz.”
