There’s word that President Biden’s chief of staff may soon leave the administration. White House chief of staff Ron Klain is preparing to leave his job in the coming weeks, according to a person familiar with Klain’s plans. He has spent more than two years as the president’s top aide and has overseen a West Wing that has been largely free of drama and staff turnover. Klain’s expected departure comes as the White House struggles to contain the fallout after the discovery of classified documents in Mr. Biden’s Delaware home and former office.
