Ron Klain

Ronald Alan Klain (born August 8, 1961) is an American attorney and Democratic political advisor who served as White House chief of staff under President Joe Biden from January 2021 to February 2023, marking the longest tenure of any initial chief of staff in a Democratic presidential administration. Klain, a graduate of Georgetown University (BA summa cum laude, 1983) and Harvard Law School (JD magna cum laude, 1987), began his career as a law clerk to Supreme Court Justice Byron White and advanced through senior roles in Democratic administrations, including chief of staff to Vice President Al Gore (1995–1999), during which he managed the 2000 presidential election recount in Florida, and Ebola Response Coordinator (2014–2015) under President Barack Obama. He also served as chief of staff to Vice President Biden (2011) and held positions in the Clinton administration as associate counsel to the president and chief of staff to Attorney General Janet Reno.

Klain's tenure as Biden's chief of staff oversaw legislative priorities including infrastructure and COVID-19 response efforts, though his time drew scrutiny for a Hatch Act violation in 2022, when he tweeted a partisan endorsement from his official account, prompting a finding of improper political activity by the Office of Special Counsel. After departing the White House, Klain rejoined the law firm O'Melveny & Myers as a partner, leveraging his experience in government and private sector advising. His career reflects a consistent focus on high-level executive operations within Democratic politics, spanning crisis management and policy implementation across multiple presidencies.
