President Donald Trump said he’s signing an executive order to instruct the Pentagon and the Department of Homeland Security to prepare a 30,000-person migrant facility at the Guantánamo Bay Naval Base in Cuba.

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.

Trump made the announcement before he signed the Laken Riley Act into law as his administration's first piece of legislation.
