Another federal appeals court could hand President Donald Trump a victory in his legal war over mandatory detention for illegal immigration, as a panel on the U.S. Court of Appeals for the 8th Circuit appeared friendly to the administration’s stance during arguments on Thursday.

The Trump administration won a key legal victory in the U.S. Court of Appeals for the 5th Circuit earlier this month, when the appeals court upheld the Trump administration’s illegal immigrant mandatory detention policy, rejecting claims by opponents of the administration that bond hearings are required for illegal immigrants. The ruling was the first time an appeals court had upheld the policy, after the administration faced hundreds of losses in federal district courts, as the problem inches closer to the Supreme Court.
