On "The Kelly File" Monday night, host Megyn Kelly and guest Howard Kurtz attacked NBC for the "gratuitous grandstanding" with which it fired Donald Trump from "Celebrity Apprentice," saying that if the network had been genuinely offended by his disparaging statements about Mexicans, it would have dismissed him weeks ago.NBC announced on Monday that it was severing ties with Trump for referring to Mexican immigrants as drug- and gun-smuggling rapists at his campaign launch.
