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.

The immigrants living in the U.S. illegally who will be sent to the detention facility are those who have committed crimes, President Trump said.

President Donald Trump ordered construction of a deportee detention camp with room for 30,000 migrants on the U.S. naval base in Cuba.

While signing Laken Riley Act on Thursday, Donald Trump announced that his administration planned to send the “worst criminal aliens” to a detention center in Guantanamo Bay, Cuba.

Critics, including the human rights organization Amnesty International, slammed President Donald Trump ’s announcement about opening a detention center at Cuba’s Guantánamo Bay to house up to 30,000 undocumented immigrants. “We’re going to send them out to Guantánamo,” the president said Wednesday, just before signing the Laken Riley Act into law.

President Donald Trump on Wednesday signed a memorandum directing the federal government to prepare the US Naval base at Guantanamo Bay, Cuba, to house tens of thousands of migrants.

Trump said earlier Wednesday that the U.S. has "30,000 beds in Guantánamo to detain the worst criminal illegal aliens threatening the American people."

The US President said up to 30,000 migrants who cannot be returned to their home countries will be held at the notorious naval base and military prison on the island of Cuba.
