WASHINGTON (AP) — Eric Holder, formerly second in charge at the Justice Department, is President-elect Barack Obama’s top choice to become attorney general, an Obama official and people close to the matter said Tuesday. Holder’s selection would mark Obama’s first step toward filling his Cabinet, and he would become the nation’s first black attorney general if confirmed by the Senate. Obama would be putting a career prosecutor at the helm of a department beset by low morale and internal investigations.—-Contact The Daily Reveille’s news staff at [email protected]
