On his show last night, Sean Hannity admitted to using video from Glenn Beck's 9/12 rally to illustrate a story on a GOP health care protest that took place last week. Jon Stewart pointed out the "inadvertent mistake," as Hannity called it, on The Daily Show last night. "It pains me to say: Jon Stewart was right," Hannity said last night, before adding that he would have gotten away with it, if it wasn't for that meddling comedian. [Media Decoder/NYT]
