Relatives of many deported Venezuelans and their lawyers have denied that they are Tren de Aragua members and have said they were never given the chance to contest the Trump administration's allegations of gang affiliation.

A judge has expressed skepticism that the notice informs Venezuelan migrants of their right to legally challenge their removals.

U.S. District Judge Paula Xinis said the administration is attempting to “obstruct” efforts to unearth details about Abrego Garcia’s improper deportation to El Salvador and had provided “vague” and “evasive” answers to court-ordered inquiries as part of an ongoing lawsuit.
