WASHINGTON (AP) — Defense Secretary Pete Hegseth says bases in Indiana and New Jersey can house detained immigrants without affecting military readiness — a step toward potentially detaining thousands of people on bases on U.S. soil.

Hegseth notified members of Congress from both states this week of the proposal to temporarily house detained immigrants at Camp Atterbury in Indiana, and Joint Base McGuire-Dix-Lakehurst in New Jersey.

President Donald Trump has moved to aggressively detain and deport people in the country illegally, a push that has swept up large numbers of immigrants, including many with no prior criminal records, and forced federal authorities to find places to house them.

Hegseth said the presence of the detainees would not negatively affect the bases’ operations or training. Officials have not said when detainees could begin arriving at the facilities or if other military bases are under consideration.

Speaking to reporters outside the White House, Trump’s border czar Tom Homan said there are about 60,000 beds currently available for detained immigrants and the goal is to expand to 100,000.

“We’re looking for any available bed space we can get that meets the detention standards we’re accustomed to,” Homan said Friday. “The faster we get the beds, the more people we can take off the street.”

Democratic lawmakers from both states and civil rights advocates condemned the idea of housing immigrants at the bases, questioning the impact on military resources and the justification for so many detentions.

“Using our country’s military to detain and hold undocumented immigrants jeopardizes military preparedness and paves the way for (Immigration and Customs Enforcement) raids in every New Jersey community,” New Jersey’s Democratic delegation said in a statement.

Democratic Rep. Andre Carson of Indiana said his questions about detainee conditions have gone unanswered by the Trump administration.

He cited concerns raised about conditions at other facilities and said, “The fact that ICE has detained so many individuals that they now need to expand detention space in Indiana is disturbing.”

Amol Sinha, executive director of the American Civil Liberties Union of New Jersey, said in a statement that housing immigrants in military facilities sets a dangerous precedent “and is contrary to the values embedded in our Constitution.”

Both of the bases identified by Hegseth have housed Afghan or Ukrainian refugees in recent years.

During Trump’s first administration, he authorized the use of military bases to detain immigrant children — including Army installations at Fort Bliss and Goodfellow Air Force Base in Texas.

In 2014, President Barack Obama temporarily relied on military bases to detain immigrant children while ramping up privately operated family detention centers to hold many of the tens of thousands of Central American families who crossed the border.
