Several poor countries, mostly in Africa, have agreed to take deportees from the United States as part of U.S. President Donald Trump's crackdown on undocumented migrants. What motivates them?

The African nations of Rwanda, South Sudan and Eswatini have already accepted deportees — almost entirely citizens of other countries — as has El Salvador in Central America.

Uganda, too, has agreed to take deportees, including one of the most high-profile cases, a Salvadoran man named Kilmar Armando Abrego Garcia, who was wrongly deported to El Salvador in March and alleges torture in prison there before being returned to the United States.
