Knoller joined CBS News in 1988 and became a prominent figure in political journalism, particularly known for his role as a White House correspondent. He worked at CBS until 2020, covering eight presidential administrations. In his later years, he transitioned to using social media to share news, amassing nearly 300,000 followers on Twitter, where he provided updates on White House activities.

Tom Cibrowski, president and executive editor of CBS News, praised Knoller, stating, "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."

Born on February 20, 1952, in Brooklyn, New York, Knoller graduated from New York University. He began his career in media as an intern and copy boy at WNEW Radio, eventually becoming a weekend reporter. In 1975, he joined the Associated Press Radio Network, where he worked for 13 years before moving to CBS News.

Initially, Knoller served as an assignment editor at CBS News' Washington Bureau. However, he soon transitioned to his dream role as a White House correspondent for CBS Radio. Throughout his career, he covered significant events, including the final year of George H.W. Bush's presidency, both terms of Bill Clinton, George W. Bush, Barack Obama, and the first term of Donald Trump.

Major Garrett, CBS News' chief White House correspondent, reflected on Knoller's impact, saying, "Mark defined what it means to chronicle and cover the White House. He was the most devoted, tenacious, and clear-eyed journalist I have ever had the honor of knowing. For as long as I live, I will count among my life’s greatest blessings that I was able to work alongside him."

Colleagues remembered Knoller not only for his professional achievements but also for his character. Norah O'Donnell, a senior correspondent at CBS News, described him as "simply the best, a legendary White House journalist who was a delight to be around. His work was his life. He was kind, funny, and always gracious in sharing his encyclopedic knowledge of the presidency."

Jim Axelrod, chief investigative correspondent for CBS News, highlighted Knoller's generosity, stating, "As impressive as Mark Knoller’s sweep of knowledge about the White House and the presidency was – it was surpassed only by his generosity toward his many friends and colleagues. He always answered with kindness, class, and a sincere desire to help."
