The Trump administration-led justice department planned to send armed US marshals to deliver a letter warning a career pardon attorney about testifying to Congress after she says she was fired over a case involving the actor Mel Gibson, her lawyer said in a letter seen by Reuters on Monday. "This highly unusual step of directing armed law enforcement officers to the home of a former Department of Justice employee who has engaged in no misconduct, let alone criminal conduct, simply to deliver a letter, is both unprecedented and completely inappropriate," Michael Bromwich, a lawyer representing the fired pardon attorney Liz Oyer, wrote to the justice department.
