Charles Krauthammer, the Pulitzer Prize-winning columnist and pundit who helped shape and occasionally dissented from the conservative movement as he evolved from "Great Society" Democrat to Iraq War cheerleader to denouncer of Donald Trump, has died at age 68. His death was announced Thursday by two longtime employers, Fox News Channel and The Washington Post. Krauthammer had said publicly a year ago he was being treated for a cancerous tumor in his abdomen and earlier this month revealed that he likely had just weeks to live.
