Ron Klain, President Joe Biden’s top aide and White House chief of staff, is expected to soon step down from his post. This news comes only weeks after the President’s State of the Union address.

Sources close to the White House have confirmed that Klain will be leaving his post in the upcoming weeks. It is unclear what his plans are after his departure.

The New York Times has reported that former Boston Mayor Marty Walsh is one of the top candidates to replace Klain. Walsh served as mayor of Boston from 2014 to 2021 and was previously Secretary of Labor for the state of Massachusetts.

Klain has served as Biden’s top aide since the beginning of his presidency. During his time in office, Klain has been a key figure in the administration’s response to the coronavirus pandemic.

It is unclear when an official announcement regarding Klain’s departure and a replacement will be made. However, it is expected that the White House will make an announcement in the coming weeks.
