From USA TODAY.

Abrego Garcia, 29, was deported by "an administrative error" to El Salvador and sent to the country’s most notorious prison on March 15. He remains there as a legal standoff continues between the Trump administration, U.S. federal courts, and now the Salvadoran government.

Bukele, in a meeting with President Donald Trump, said he does not have the power to return Abrego Garcia, whom he accused of being a terrorist.

The Trump administration says Abrego Garcia is a member of MS-13 gang. A U.S. district judge has disagreed, saying the administration has not provided evidence to support that accusation, according to court documents.
