Keith Olbermann is a political commentator and activist, formerly a sportscaster. He currently hosts Countdown, a nightly news and commentary program on MSNBC.
Olbermann has a history of disputes with Bill O'Reilly, the host of Fox network's "The O'Reilly Factor". One example is when he corrected O'Reilly about the execution of American soldiers in Malmedy, Belgium by Nazi SS officers. O'Reilly had reported that the American soldiers executed the Nazi soldiers. O'Reilly has also verbally attacked Olbermann on his TV and radio shows as well; in particular, on his radio program, he cuts off any guest who mentions Olbermann's name. [1]
