WHEELING, W.Va. (AP) \u2014 The U.S. attorney for West Virginia's northern district is stepping down.\r\n\r\nU.S. Attorney Bill Powell announced his resignation effective Feb 28. The move will allow President Joe Biden to appoint a successor.\r\n\r\nNominated by former President Donald Trump, Powell began his term as U.S. attorney in October 2017.\r\n\r\nHis office helped coordinate drug enforcement efforts, including prosecutions of health care fraud involving physicians and pharmacists.
