A federal judge in Maryland will hear arguments Friday over whether the Trump administration can invoke the state secrets privilege to withhold information about bringing Kilmar Abrego Garcia back to the United States.

The government claims he’s a member of the MS-13 gang, which his wife and attorney deny, and deported him to El Salvador despite a judge’s 2019 order barring him from being sent there.

Questions over privileged documents and possible state secrets were the main focus of an hours-long hearing Friday afternoon in the case of a Maryland man mistakenly deported by the Trump administration.
