The wife of a Maryland man who was mistakenly deported to a notorious prison in El Salvador is calling for his return to the U.S.

A U.S. judge in Maryland is scheduled to hear arguments on Friday over the erroneous deportation of a Salvadoran man who was flown to El Salvador last month as part of an agreement by President Donald Trump's administration with that country's government to detain alleged gang members.

Abrego Garcia, who had fled El Salvador as a teenager to escape gang violence, was expelled and sent back to his native land even though he had won a court order six years earlier barring his removal.
