A federal judge in Maryland signaled on Friday that she may soon issue a ruling that could delay the Trump administration’s order to deport Kilmar Abrego Garcia to a third country quickly if he is released next week from U.S. Marshals’ custody in Tennessee.

Judge Paula Xinis, an appointee of former President Barack Obama, said she was “deeply concerned” that, absent a court order, the Department of Homeland Security would immediately arrange for Abrego Garcia’s deportation to an undisclosed country before he could have a chance to challenge the removal.
