Rupert Murdoch's global media empire is coming under further pressure this morning as the scandal starts to affect his interests in other countries. Our partner, the BBC has learned U.S. federal investigators have contacted British police to discuss the probe into allegations against journalists working for the News of the World newspaper. Some are alleged to have paid police officers for information. Murdoch's News Corporation is based in the U.S., and the law here can impose serious penalties on companies guilty of bribing foreign officials. In the country of Murdoch's birth, Australia, the value of News Corporation shares has plunged more than six percent to a two-year low. Sarah Ellison, contributing editor at Vanity Fair and author of "War at the Wall Street Journal: Inside the Struggle To Control an American Business Empire," believes there's a possibly News Corp. may be split apart before the scandal is over.
