From Launch Music News: If you're sick of celebrities using their status to lecture us about their "causes du jour" from the esteemed pulpit of Capitol Hill, you're not alone. Ohio Senator George Voinovich is looking to limit the time celebrities have been getting in Washington lately. The proverbial last straw for Voinovich was Backstreet Boy Kevin Richardson's planned testimony before a Senate Environment And Public Works Clean Air Subcommittee hearing dealing with mining. According to The Washington Post, Voinovich announced that he'd boycott the Backstreet Boy's testimony, saying, "It's just a joke to think that this witness can provide members of the United States Senate with information on important geological and water-quality issues."
