Fox News commentator Charles Krauthammer dies at 68

Conservative commentator and Pulitzer Prize winner Charles Krauthammer has died at age 68.

Fox News made the announcement Thursday.

Krauthammer was a well-known contributor on the network.

He was also a Harvard-trained psychiatrist and a best-selling author.

Just weeks ago, he wrote a heartbreaking letter explaining that his cancer had returned and he only had a few weeks left to live.

Despite a successful surgery in August to remove the cancer from his abdomen he said it returned and spread rapidly.

He is survived by his wife and son.
