Kilmar Abrego Garcia, a protected legal resident from El Salvador, was deported from Maryland due to an "administrative error" acknowledged by the Trump administration, leading to legal proceedings scheduled for review by a federal judge. Garcia and his U.S. citizen wife have filed a lawsuit seeking his return, citing a 2019 judicial protection that should have prevented the deportation, and are also requesting a halt to payments to the high-security prison in El Salvador where he is held. The case underscores the complexities of immigration enforcement and the significant impact of administrative oversights on individuals with legal protections.
