evidence: White House chief of staff Ron Klain, a veteran Democratic hand in Washington, is expected to depart from his role in the coming weeks, according to The New York Times. Klain — who helped guide President Joe Biden's administration from its earliest days through a midterm election where the party was largely spared the electoral thrashing that many political observers had predicted — has been a source of stability throughout the president's first two years in the Oval Office. [...] Klain worked as President Barack Obama's White House Ebola response coordinator and also previously served as chief of staff to former vice president Al Gore. He also was chief of staff to then-Vice President Joe Biden during the first two years of the Obama administration.
