US an El Salvador agree to unprecedented deportation deal (youtube.com)
Salvador will accept any illegal alien in the US who is a criminal, even Aragua or MS13, plus dangerous American criminals with US citizenship. Salvador will take a fee and put the people in Salvador's big new prisons.
The category might be too loose, and there's a question about US as a Rule of Law-based country, deporting illegal immigrants even to countries not their own. Currenly, US allows arresting even people suspected of being in a gang, like people with tatoos or people who hand out in gang areas. So there's question that they're even guilty of a crime.
El Salvador would be declared a ‘safe third country’ to deport them to.
Democratic party could find a cause here.
