The Trump administration is planning to dramatically ramp up sending undocumented migrants to Guantanamo Bay starting this week, with at least 9,000 people being vetted for transfer, according to documents obtained by POLITICO.

That would be an exponential increase from the roughly 500 migrants who have been held for short periods at the base since February and a major step toward realizing a plan President Donald Trump announced in January to use the facility to hold as many as 30,000 migrants.

The transfers to Guantanamo could start as soon as Wednesday, the documents state. The expectation is that the detainees would be at the facility temporarily before being deported to their countries of origin.
