Charles Krauthammer (; born March 13, 1950) is an American syndicated columnist, author, political commentator, and former physician whose weekly column is syndicated to more than 400 publications worldwide. While in his first year studying at Harvard Medical School, Krauthammer became permanently paralyzed from the neck down after a diving accident, severing the spinal cord at C5. After spending 14 months recovering in a hospital, he returned to medical school, graduating to become a psychiatrist involved in the creation of the Diagnostic and Statistical Manual of Mental Disorders III, and later developing a career as a Pulitzer Prize-winning writer. He was a weekly panelist on PBS news program Inside Washington from 1990 until it ceased production in December 2013.

Krauthammer criticized President George W. Bush's nomination of Harriet Miers to succeed Supreme Court Justice Sandra Day O'Connor. He called the nomination of Miers a "mistake" on several occasions. He noted her lack of constitutional experience as the main obstacle to her nomination.  On October 21, 2005, Krauthammer published "Miers: The Only Exit Strategy", in which he explained that all of Miers's relevant constitutional writings are protected by both attorney-client privilege and executive privilege, which presented a unique face-saving solution to the mistake: "Miers withdraws out of respect for both the Senate and the executive's prerogatives." Six days later, Miers withdrew, employing that argument: "As I stated in my acceptance remarks in the Oval Office, the strength and independence of our three branches of government are critical to the continued success of this great Nation. Repeatedly in the course of the process of confirmation for nominees for other positions, I have steadfastly maintained that the independence of the Executive Branch be preserved and its confidential documents and information not be released to further a confirmation process. I feel compelled to adhere to this position, especially related to my own nomination. Protection of the prerogatives of the Executive Branch and continued pursuit of my confirmation are in tension. I have decided that seeking my confirmation should yield."  The same day, NPR noted, "Krauthammer's scenario played out almost exactly as he wrote." Columnist E.J. Dionne wrote that the White House was following Krauthammer's strategy "almost to the letter". A few weeks later, the New York Times reported that Krauthammer's "exit strategy" was "exactly what happened," and that Krauthammer "had no prior inkling from the administration that they were taking that route; he has subsequently gotten credit for giving [the Bush administration] a plan."
