Trump says U.S. will send "worst criminal illegal aliens" to Guantanamo Bay

President Trump on Wednesday announced he's signing an executive order instructing the Pentagon and Department of Homeland Security to prep Guantanamo Bay for use as a migrant detention facility for "the worst criminal illegal aliens threatening the American people."

The president made the announcement from the White House before he signed the Laken Riley Act, a new law that expands the mandatory detention of migrants to include noncitizens who are charged with burglary, larceny, theft or shoplifting. The law is named after a 22-year-old nursing student, Laken Riley, who was murdered by an undocumented Venezuelan immigrant. 

Mr. Trump said Guantanamo Bay has 30,0000 beds available, and "most people don't even know about it."
