In a note to readers on June 8, he wrote that his fight is over and he thanked his family, doctors, and colleagues and expressed satisfaction in what his life had been. He later became a panelist on PBS' "Inside Washington" and eventually joined Fox News as a political analyst.

"I am sad to leave, but I leave with the knowledge that I lived the life that I intended". A Washington Post reporter tweeted a photo of the in memoriam, which showed Krauthammer's photo displayed above the outfield.
