An 'administrative error' sent a Maryland father of a 5-year-old autistic son to prison in El Salvador. His family is fighting for his return.

Lawyers for a Maryland man who was mistakenly deported to El Salvador will ask a federal judge to order the U.S. to return him.

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.

In an exclusive interview, the wife of a Maryland migrant spoke to CBS News after the Trump administration admitted to mistakenly deporting the man to a notorious El Salvador prison due to an "administrative error.

Three bills, collectively known as Maryland’s Immigrant Justice Protection Package, aimed at protecting the rights of Maryland’s immigrant community are moving through the Maryland General Assembly.

This latest case, in which lawyers argue their client had no proven links to MS-13, adds to the growing judicial and public scrutiny about the deportations to El Salvador's notorious mega-prison.

The case has raised questions not only about how the man could have ended up on a plane to El Salvador, but also about why the administration has apparently not moved to correct its mistake.

The Trump administration is blaming an “error” for wrongfully deporting Maryland resident and father Kilmar Abrego Garcia to El Salvador. Now, the administration says they cannot bring him back since he is no longer in U.

The women’s accounts raise questions about the thoroughness of the administration’s vetting of migrants it has sent to the notorious prison.
