The Donald Trump administration has started sending flights of undocumented migrants in the United States to Guantanamo Bay. The US has ... previously used a Guantanamo Bay camp to detain certain migrants, but Trump's use is different, immigration experts have said. On January 29, Trump signed a memo directing the departments of defence and homeland security to expand the Migrant Operations Centre at Guantanamo Bay to "provide additional detention space for high-priority criminal aliens unlawfully present in the United States". Historically, the US has used Guantanamo Bay to hold migrants stopped at sea. Now, Trump is sending people who were detained on US soil. Trump says he plans to detain 30,000 people. That many people haven't been detained at Guantanamo Bay since the 1990s. Migrants at Guantanamo Bay lack "access to basic human necessities, appropriate medical care, education, and potable water," the [International Refugee Assistance Project] said in [a] report. Migrants don't have access to unmonitored calls with lawyers and can't candidly speak about poor conditions at the naval base. "The US government intentionally uses Guantanamo in hopes of avoiding oversight and the public eye, which makes the facility ripe for abuse," [interim senior policy director at the International Refugee Assistance Project Hannah] Flamm said.
