The Justice Department argued before an appeals court panel on Tuesday that the Trump administration should be allowed to continue with a Biden-era mass parole program for hundreds of thousands of migrants, leaning on a Supreme Court order issued in May as part of the argument.

The three-judge panel on the United States Court of Appeals for the First Circuit heard arguments in the DOJ’s appeal of a lower court’s order, which had blocked the Trump administration’s revocation of work permits and legal status for over 530,000 migrants flown into the United States under a Biden administration program.
