U.S. District Judge James Boasberg said there is cause to hold the Trump administration in criminal contempt for ignoring his orders over flights containing migrants who were sent to El Salvador.

In a lengthy ruling issued Wednesday, the judge said there was sufficient evidence to show a “willful disregard” by the administration of his orders in March that directed officials to halt the flight of more than 130 Venezuelan migrants to the CECOT prison in El Salvador without any due process.

For the last several weeks, Boasberg has grilled officials about the flights, pressing for details on when the government started hauling people out of the United States and who specifically made those orders. Prosecutors have dodged his questions routinely, claiming state secret privileges over information or flatly asserting that they simply don’t know who instructed the planes to keep going even after his order was issued.
