A federal judge ruled on Wednesday that the Trump administration must give more than 100 migrants sent to a notorious prison in El Salvador prison a chance to challenge their deportations.

Administration officials have either violated orders or used an array of obfuscations and delays to prevent federal judges from deciding whether violations took place.
