RFK Jr. Calls Sen. Inhofe Big Oil 'Prostitute' Popular insult jumps political divide By Mary Papenfuss, Newser User Posted Mar 7, 2012 4:02 AM CST 21 comments Comments GOP Sen. James Inhofe. (Getty Images) (Newser) – The prostitute insult has jumped the aisle. Democrat Robert Kennedy Jr. is calling Oklahoma Sen. James Inhofe a hooker for getting into bed with Big Oil. "Speaking of prostitutes, Big Oil’s top call girl, Sen. Inhofe, wants to kill fuel economy backed by automakers, small biz, enviros, and consumers," tweeted Kennedy, a senior attorney at the Natural Resources Defense Council who also happens to be a syndicated radio host. The tweet was apparently in response to a letter the GOP senator sent to the EPA, accusing the administration of “recklessly” implementing emissions standards for cars, reports ABC.
