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 Donald Trump, who made the deportation of immigrants a central part of his campaign and presidency, said Wednesday that the U.S. will use a detention center at Guantánamo Bay, Cuba, to hold tens of thousands of the “worst criminal aliens.

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