The new Trump administration is already preparing to significantly increase its detention capacity illegal immigrants as part of the mass eviction operation it pledged to launch in January, Fox News Digital has confirmed – the latest sign that it plans to keep that promise.

President-elect Trump said during the campaign that he intended to launch a historic campaign of mass expulsions in the wake of the historic migrant crisis at the southern border. It’s a promise he and top officials have repeated since his election victory last week.

Karoline Leavitt, a spokesperson for the transition team, told Fox News Digital: “The American people re-elected President Trump by a resounding margin, giving him a mandate to implement the promises he made during the election campaign. He will hold them.”

GOVERNOR DEM THREATENS TO USE ‘EVERY TOOL’ TO FIGHT TRUMP-ERA DEPORTATIONS

NBC News reported this week that the Trump administration was considering locations where it could expand immigration detention centers and that the transition team was studying how many migrants could be detained in regions across the country and talking with private prison companies about expansion.

A source close to the plans confirmed the information. NBC reported that the plan was to double the number of Immigration and Customs Enforcement (ICE) beds allocated by Congress, but the source said the intention was to significantly increase the number of beds and double the ability was too specific.

Locations should be expanded near areas where there have been significant numbers of illegal immigrants. “Sanctuary” cities Cities like New York, Washington DC and Chicago have been overwhelmed by an influx of migrants into their jurisdictions, some of whom were bused in from Texas, so detention centers could be created, expanded or reopened in those areas .

“LIBERATION DAY”: WHAT TO EXPECT FROM PRESIDENT-ELECT TRUMP ON BORDER SECURITY AND IMMIGRATION

There are currently a number of ICE facilities that are not operating at full capacity or whose capacity could be increased. Some cases are unique, like a facility in Adelanto, California, that was largely closed due to a COVID-era court order.

Republicans have repeatedly pressed the Biden administration to reduce the level of expulsions, even in the context of a historic influx of migrants into the interior of the United States. Critics of the Trump plan said the cost would be too high, but immigration hawks said it would cost less than allowing them to stay.

The administration could face significant resistance from Democratic governors. Mass Governor, Maura Healey said last week that “all available tools must be used to protect our citizens, to protect our residents and to protect our states and to maintain the course on democracy and the rule of law as fundamental principles.”

“No. Absolutely not,” she said when asked if state police would assist with evictions.
