Migrant detainees being held in Florida’s “Alligator Alcatraz” have claimed conditions at the detention center are “grim,” citing how they’ve been fed “cold ham sandwiches,” according to The Washington Post.

The lawsuit says attorneys have been repeatedly turned away from the detention camp and had virtual meetings mysteriously canceled.

The ACLU, ACLU of Florida and Americans for Immigrant Justice are working with detainees and other groups representing them, including Florida Keys Immigration, Sanctuary of the South, U.S. Immigration Law Counsel, Victoria Slatton of Sanabria & Associates, and the Law Offices of Catherine Perez, PLLC.

ICE detention standards are difficult to enforce because they aren’t written into law. Rather than follow a uniform standard, detention centers operate under a patchwork of different standards.
