A judge is hearing arguments Thursday over whether the Trump administration defied a court order when they deported alleged migrant gang members to El Salvador.

Justice Department attorneys will appear before Judge James Boasberg on Thursday to make its case for why the Trump administration did not violate his orders halting the use of the Alien Enemies Act to deport Venezuelans the government has accused of being part of a gang.

The judge, James E. Boasberg, said he was likely to wait until next week to rule on whether the White House was in contempt of court for having ignored his order.
