June 21 (UPI) -- Conservative columnist Charles Krauthammer died Thursday, Fox News announced. He was 68.
On June 8, Krauthammer revealed he had only a few weeks to live due to cancer in his abdomen, which returned after surgery to remove a tumor last year.
"I leave this life with no regrets," Krauthammer wrote at the time. "It was a wonderful life -- full and complete with the great loves and great endeavors that make it worth living. I am sad to leave, but I leave with the knowledge that I lived the life that I intended."
News of Krauthammer's death brought reactions from conservative politicians and personalities.
"Charles Krauthammer was a man of extraordinary intellect," Sen. Marco Rubio, R-Fla., tweeted. "Truly one of a kind. The conservative movement & the nation will miss his incredible insight, especially in times such as these. We offer our deepest condolences to his family. May he Rest In Peace."
Krauthammer had been a columnist at The Washington Post since 1984. In 1987, he won the Pulitzer Prize in commentary for his "witty and insightful columns on national issues."
He also was a regular on Fox News for several years.
"I am sure you will be owning the panel discussion in heaven as well," tweeted Fox News anchor Bret Baier. "And we'll make sure your wise words and thoughts -- your legacy -- will live on here."
