As the next White House Chief of Staff, US President Joe Biden has appointed Jeff Zients, a longtime assistant who oversaw his extensive COVID-19 response organization. Zients previously served in the Obama administration.

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.

“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 have 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.

Zients, who managed the vast Covid-19 pandemic response when Biden joined the office, is regarded as a capable technocrat who will work to ensure that the earlier legislative triumphs are carried out while lacking Klain's extensive political contacts.
