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

After meeting Secretary of State Marco Rubio, El Salvador's president has offered to house U.S. deportees and even American inmates in his country's "mega-prison."

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.
