The position of White House Chief of Staff, the person closest to the President on a daily basis, has existed since the Truman Presidency after World War II.
Some have lasted very short times in that position; some have proved to be disasters; and a small number have turned out to be exceptional in their dedication to progress under their Presidents.
The true disasters include:
Sherman Adams under Dwight D. Eisenhower (1953-1958)
H. R. Haldeman under Richard Nixon (1969-1973)
Donald Rumsfeld under Gerald Ford (1974-1975)
Dick Cheney under Gerald Ford (1975-1977)
Hamilton Jordan under Jimmy Carter (1979-1980)
Donald Regan under Ronald Reagan (1985-1987)
Reince Priebus under Donald Trump (six months in 2017)
Mark Meadows under Donald Trump (2020-2021)
The success stories include:
Kenneth O’Donnell under John F. Kennedy (1961-1963)
James Baker under Ronald Reagan (1981-1985)
Howard Baker under Ronald Reagan (1987-1988)
John Sununu under George H. W. Bush (1989-1991)
Leon Panetta under Bill Clinton (1994-1997)
Erskine Bowles under Bill Clinton (1997-1998)
John Podesta under Bill Clinton (1998-2001)
Andrew Card under George W. Bush (2001-2005)
Denis McDonough under Barack Obama (2013-2017)
John F. Kelly under Donald Trump ((2017-2019)
Ron Klain under Joe Biden (2021- )
When one looks at these lists, it is clear that Ron Klain stands out as one of the top few White House Chiefs of Staff of all time, with Kenneth O’Donnell, James Baker, Leon Panetta, Andrew Card, and Denis McDonough also on the list of the best!
