Current laws “would categorically preclude most U.S. citizens and residents from serving their sentence in El Salvador,” a former U.S. attorney said.

El Salvador’s strongman President Nayib Bukele announced his country has offered the U.S. the opportunity to “outsource part of its prison system.”

Bukele had offered to take in people deported from the US, regardless of their nationality, and house them in El Salvador's mega-jail. "We can send them and he will put them in his jails," Rubio said.
