Charles Krauthammer, a longtime Fox News contributor, Pulitzer Prize winner, Harvard-trained psychiatrist and best-selling author who came to be known as the dean of conservative commentators, has died. He was 68.

His death had been expected after he wrote a heartbreaking letter to colleagues, friends and viewers on June 8 that said in part "I have been uncharacteristically silent these past ten months. I had thought that silence would soon be coming to an end, but I'm afraid I must tell you now that fate has decided on a different course for me...

"Recent tests have revealed that the cancer has returned. There was no sign of it as recently as a month ago, which means it is aggressive and spreading rapidly. My doctors tell me their best estimate is that I have only a few weeks left to live. This is the final verdict. My fight is over."

In recent years, Krauthammer was best known for his nightly appearance as a panelist on Fox News' "Special Report with Bret Baier" and as a commentator on various Fox news shows.

Following the news of the death of his "good friend," Baier posted onĀ Twitter, "I am sure you will be owning the panel discussion in heaven as well. And we'll make sure your wise words and thoughts - your legacy - will live on here."
