Two of the Senate's most prominent critics of Hollywood, Sam Brownback and Joseph Lieberman, were in Los Angeles on Wednesday, where they held a news conference urging the entertainment industry to limit excessive violence and sexual content in the media. Their plea came just months after the senators - along with 8,500 other people -- signed an ""Appeal to Hollywood"" in July, in which they asked industry executives to develop a new, voluntary code of conduct that would ""establish certain minimum standards for violent, sexual and degrading material for each medium."" In anticipation of their trip, ads were placed in various papers reprinting the ""Appeal to Hollywood"" in full. The document was signed by such high-profile figures as former presidents Jimmy Carter and Gerald Ford, retired generals Colin Powell and Norman Schwarzkopf, former Education Secretary William Bennett and entertainers Steve Allen and Naomi Judd.Source: The Hollywood Reporter
