Relatives and attorneys seek answers on the men sent to the high-security prison as the Venezuelan government calls for their return.

The 31-year-old is among multiple migrants whose family members or lawyers have said were wrongly accused by the Trump administration of gang affiliation and deported to a notoriously strict El Salvador earlier this month.

A team of lawyers representing the families of 30 Venezuelans sent by the United States to a mega prison in El Salvador asked the Salvadoran Supreme Court of Justice on Monday to evaluate the legality of their detention.
