El Salvador has agreed to house violent US criminals and receive deportees of any nationality, officials from both countries announced Monday, in an unprecedented deal with the Trump administration that has alarmed critics and rights groups.

El Salvador has agreed to take deportees from the United States and violent criminals from U.S. prisons in an "extraordinary migratory agreement," which Secretary of State Marco Rubio announced Monday.

Secretary of State Marco Rubio praised President Nayib Bukele’s “unprecedented, extraordinary” proposal to accept any convicted criminal deported by the United States.
