The Pentagon on Friday said it had transferred an Afghan detainee who was held at Guantanamo Bay for 15 years, a move that comes after a court ruled the United States had no legal justification to hold him.
Opened under Republican President George W. Bush, the Guantanamo Bay prison had its population peak at about 800 inmates. President Barack Obama, a Democrat like Biden, whittled down the number, but his effort to close the prison was stymied largely by Republican opposition in Congress.
