Top Biden aide Ron Klain soon to leave White House

US White House Chief of Staff Ron Klain, who has spent more than two years as President Joe Biden's top aide, is preparing to leave his job in the coming weeks, according to a person familiar with Klain's plans.

Klain's expected departure comes not long after the White House and Democrats had a better-than-expected showing in the November elections, buoyed by a series of major legislative accomplishments, including a bipartisan infrastructure bill and a sweeping climate, health care and tax package that all Republicans rejected. His tenure as chief of staff is the longest for a Democratic president in modern times.
