The Department of Defense (DOD) confirmed the arrival of the first 10 “high threat” illegal migrant criminals to the U.S.’s most secure prison – the Guantánamo Bay Detention Camp – in Cuba, all of whom are members of the violent Venezuelan criminal group Tren de Aragua (TdA).

TdA is an international criminal group that has been terrorizing U.S. communities from New York City to Colorado. As one of his first actions, President Donald Trump issued an executive order on Jan. 20 instructing the State Department and other government agencies to move to designate TdA as a “foreign terrorist organization.”

On Thursday, ICE and other federal law enforcement agencies conducted a series of raids in Aurora, Colorado, resulting in the arrest of over 100 TdA members.

The DOD stated that these migrant criminals are being housed in vacant detention facilities. The DOD said that is only a temporary arrangement being made to “ensure the safe and secure detention of these individuals until they can be transported to their country of origin or other appropriate destination.”

DHS clarified that the Guantánamo Bay prison will be used to house only “the worst of the worst” criminals.

Commenting on the arrests of the over 100 TdA members on Wednesday, Joseph Humire, executive director of the Center for a Secure Free Society and an expert on TdA, told Fox News Digital that Trump’s latest moves are “tremendously significant” that shows that there is a “new attitude” against TdA in the U.S.

“That’s what’s needed to be able to dismantle them and eventually deport them from the United States,” he said. “This is a foreign terrorist organization that has been spreading throughout the United States for the last couple of years and doing it so very rapidly, so I think the impetus is on the United States to use all the elements of our national security to be able to dismantle them from within.”
