President Joe Biden on Friday named his former top Covid-19 aide Jeff Zients to White House chief of staff -- one of the most crucial positions in an administration gearing up for a likely re-election campaign.
Zients replaces Ron Klain, who saw Biden through the first two years of his term in the post, arguably the most powerful behind-the-scenes job in any US administration. The swap will take place on February 8, a day after Biden delivers his State of the Union address to Congress.
The departure of Klain, who has worked with Biden throughout his decades-long Washington career -- from senator to vice president, then victor over Donald Trump in 2020 -- will deprive the 80-year-old president of an especially close, trusted aide.
Chiefs of staff do everything from managing access to the president, setting his agenda, communicating with political power brokers and acting as a constant crisis manager and sounding board for ideas.
"During the last 36 years, Ron and I have been through some real battles together. And when you’re in the trenches with somebody for as long as I have been with Ron, you really get to know the person. You see what they’re made of," Biden said in a statement.
Klain is credited with masterminding the intricate, behind-the-scenes negotiations between the White House and lawmakers in Congress that has seen Biden get a string of landmark bills passed, often against expectations in the last two years.
Until November's midterm elections, Democrats held a razor-thin majority in both houses of Congress and Klain was instrumental in preventing the various party factions from splitting at key moments.
On Twitter, Biden described Klain as a "once in a generation talent with fierce intellect and heart."
Zients, who oversaw the vast Covid-19 pandemic response when Biden took office, is considered a skilled technocrat, who does not have the deep political connections of Klain but will aim to make sure that the earlier legislative victories are followed through.
"A big task ahead is now implementing the laws we’ve gotten passed efficiently and fairly," AFP quoted Biden as saying.
"When I ran for office, I promised to make government work for the American people. That’s what Jeff does," Biden said. "I'm confident that Jeff will continue Ron's example of smart, steady leadership."
Biden has not yet declared he is running again but is widely expected to do so, potentially pitting him again against former President Donald Trump in 2024.
Zients will also be taking over just as Republicans flex their muscles in the House of Representatives, where they won their own tiny majority in November. With the hard-right of the party in the ascendant, Biden is due to face a series of aggressive investigations into his policies and the business activities of his son Hunter.
