According to the network, CBS News president and executive editor Tom Cibrowski said, “Mark Knoller was the hardest-working and most prolific White House correspondent of a generation.” “Everyone in America knew his distinctive voice and his up-to-the-minute reporting across eight presidential administrations.”
“I keep a daily log of everything the president does,” Knoller said once, per CBS News. “I keep a list of speeches. I keep a list of travel — foreign travel, domestic travel. A list of outings. A list of golf. A list of pardons, vetoes, states that he’s visited, and states that he hasn’t visited. Every time he goes on vacation, every visit to Camp David.”

Knoller was also recognised for his generous personality. Anyone in need could access his huge White House database, which he had spent many hours compiling.

CBS News correspondent Chip Reid wrote, “This remarkably generous man shared it with anyone who asked – reporters on deadline, historians, even White House aides filling gaps in their own records. He believed the public had a right to know.”
Knoller’s career took off in New York, and he worked his way up to the Associated Press Radio Network. In 1999, he joined CBS News and eventually became the White House correspondent for CBS Radio. In 2020, he left CBS after covering every administration from President George H.W. Bush through the first term of President Donald Trump.
Tributes poured in from across the media after news of his death.
