In order to get a better idea, do read the whole article, here I just give one small sample: "Cuba agreed in 2006 to stop its practice of harboring American fugitives."
I wonder if that means people the US considers fugitives. As he is regarded by most of the world as an asylum seeker Cuba might decide they can let him in and they are still honouring that agreement.
