Renowned CBS News Correspondent Mark Knoller Dies at 73

Mark Knoller, the legendary CBS News correspondent renowned for his meticulous White House reporting and unofficial role as presidential historian, has passed away at the age of 73. He died in Washington, D.C., according to a close friend, though the cause of death was not immediately disclosed. Knoller had been battling diabetes and experiencing ill health.
For decades, Knoller was an indispensable figure in the White House press corps, known for his extraordinary dedication to chronicling every presidential action, movement, and utterance. Frustrated by the absence of a centralized database, he single-handedly created an immense, detailed log of presidential activities, travel, speeches, and even golf outings, filling a significant void in American historical records.
Tom Cibrowski, president and executive editor of CBS News, lauded Knoller as “the hardest-working and most prolific White House correspondent of a generation,” whose distinctive voice and up-to-the-minute reporting spanned eight presidential administrations. Despite the competitive nature of journalism, Knoller was remarkably generous, sharing his vast database with fellow reporters, historians, and even White House staff, driven by his belief in the public’s right to know.
Born in Brooklyn, New York, on February 20, 1952, Knoller began his career at WNEW Radio after graduating from New York University, later spending 13 years with the Associated Press Radio Network. He joined CBS News in 1988, initially as an assignment editor, but soon found his true calling as a White House correspondent for CBS Radio, a role in which he garnered numerous prestigious journalism awards. He covered presidents from George H.W. Bush through Donald Trump, departing CBS in 2020.
In his later years at CBS, as his voice began to fail, Knoller reinvented himself, becoming a prolific presence on Twitter (now X). He amassed over 300,000 followers, sharing White House news, his famous facts and figures, and his signature wit.
Tributes poured in from former colleagues. Norah O’Donnell remembered him as “simply the best, a legendary White House journalist who was a delight to be around.” Major Garrett praised Knoller for defining what it means to cover the White House, calling him “the most devoted, tenacious and clear-eyed journalist I have ever had the honor of knowing.” Jim Axelrod highlighted Knoller’s immense knowledge and his unparalleled generosity and kindness.
