The U.S. Marine Corps, in cooperation with Immigration and Customs Enforcement (ICE), has quietly launched a pilot program to station ICE agents at three major military installations: Camp Pendleton in California, Marine Corps Base Quantico in Virginia and Marine Corps Base Hawaii. 

The move, aimed at bolstering security around these bases, has raised as many questions as it seeks to answer.

Abby Hall Blanco, a University of Tampa economics and defense professor, weighed in on the lack of transparency surrounding the program’s inception. 

“We don’t really have a whole lot of information at precisely what led up to this specific program,” she told Fox News Digital. “The program is intended to augment security, particularly around the perimeter of these Marine Corps bases.”

One of the two Jordanian nationals was later confirmed to be in the U.S. illegally, with the other a foreign student whose status was terminated, according to ICE.

Other incidents, including unauthorized drone flights over military installations and reports from The Wall Street Journal that around 100 Chinese nationals have attempted to breach U.S. military bases, add to the picture of a growing concern by the U.S. government.

Despite heightened security, Hall expressed skepticism about the implications of involving ICE.

“It gives kind of an odd impression that the Marine Corps is not handling its own security sufficiently,” she said. “Having known quite a few Marines in my time, I can’t imagine that they would find that to be a particularly flattering interpretation.”

Fox News Digital has reached out to ICE for comment.
