U.S. Secretary of State Marco Rubio on Tuesday called an offer by El Salvador's President Nayib Bukele to house dangerous criminals from the United States in his country's jails "very generous" and said the Trump administration would have to study it.

He met with Salvadoran President Nayib Bukele and senior officials at Bukele's residence on Lake Coatepeque outside the capital for almost three hours, where they agreed to go beyond El Salvador's acceptance of its own deported citizens.
