On Monday’s O’Reilly Factor, Bill O’Reilly slammed a cartoon about NPR firing pundit Juan Williams drawn by Detroit Free Press cartoonist Mike Thompson.

In the cartoon (featured above), Fox News hosts are dressed in costumes ranging from a clown suit to a suicide bomber and a Nazi uniform, with Juan Williams commenting, “People dressed in Muslim garb make me nervous.”

“Believe me when I tell you the far left is seething over all of this NPR stuff,” O’Reilly said. “The blow back has begun. Take a look at this political cartoon in the Detroit Free Press by Mike Thompson featuring me wearing ‘Obama equals Hitler’ stuff.”

“Please don’t sink to his level but can you let him know what you think,” O’Reilly said after giving out Thompson’s e-mail address on air. “Keep it respectful but don’t be like Mike.”
