 The Justice Department is filing a lawsuit against a Texas-based company over allegations its employees sexually abused migrant children under their care. The suit accuses Southwest Key Program employees of engaging in severe sexual abuse against minors being housed by the federal-funded nonprofit. Prosecutors say many employees knew of the abuse, over 100 instances in all, but failed to stop it. The lawsuit demands a civil penalty for the victims and a court order aimed at mandating the company work to prevent future abuses.
