The FBI is just cranking up a preliminary review of whether alleged phone hacking and bribery by Rupert Murdoch's media empire violated U.S. laws, but any resolution may well have to await the outcome of British investigations, AP reported. The FBI's early fact-gathering could turn into a long saga that tests or reinforces the long-standing cooperation between U.S. and British law enforcement. Most of the records and witnesses to prove or disprove the allegations are in the hands of British investigators. The problem for Murdoch is that his business, not just his now-shuttered British tabloid News of the World, faces investigations on two continents. That includes a nascent FBI probe. Depending upon what turns up, it could head in unexpected directions, perhaps threatening other Murdoch properties, which include the Fox television network. News Corp., Murdoch's New York-headquartered parent company, is assembling a gold-plated roster of lawyers to deal with any U.S. legal action. According to published reports, the company has signed up Brendan Sullivan, the high-priced Washington criminal defense attorney, and Mark Mendelsohn, an acknowledged expert on the Foreign Corrupt Practices Act. -- SPA
