Bill O'Reilly and Charles Krauthammer debated whether the lack of celebrities willing to perform at President-elect Donald Trump's inauguration is due to their fear of being blacklisted in Hollywood.

O'Reilly said entertainers are afraid their careers could be harmed by performing for someone seen in many liberal precincts as a divisive, controversial figure.

Krauthammer countered that there was no evidence of such a prediction, remarking that Hollywood is "more than 100 percent liberal", and that they refused to perform "for their own political reasons."

"We don't have a king," he said, adding that if the United States were North Korea, entertainers would be in fear of their lives for turning down the commander-in-chief.

O'Reilly pointed to George W. Bush's 2000 inauguration having a better "cross-section" of celebrities, including Ricky Martin, Andrew Lloyd Webber and Wayne Newton.

"There is very rank fear in the entertainment industry to be associated with President-elect Trump," he said.

Of the ideological differences between Americans in the Hollywood and the universities, and other sectors, Krauthammer said, "you live with it the way you live with the weather."
