President Trump says he will use a detention center at Guantánamo Bay to hold tens of thousands of criminal immigrants in the U.S. illegally.

President Trump ordered officials to create a 30,000-person migrant facility at Guantanamo Bay for "the worst criminal illegal aliens."

The US has maintained a migrant detention facility there for decades that is separate from the notorious high-security jail for foreign terror suspects, including alleged 9/11 mastermind Khalid Sheikh Mohammed.
