Glenn Beck has one less show to host for Fox News Channel. This Friday, Beck’s live 5pm hour is being pre-empted for a taped special called, “Bad Behavior: Political Sex Scandals,” hosted by Greta Van Susteren. The special looks at the recent Anthony Weiner and Arnold Schwarzenegger scandals, as well as the high profile escapades of former Sen. John Edwards, former Gov. Mark Sanford, and former Gov. Eliot Spitzer, now a CNN host. The special airs Friday at 5pmET.
