The fallout from the News of the World  hacking scandal seems far from contained this morning, as U.S. lawmakers call for an investigation into whether any American laws were broken during the alleged hacking practices at News Corporation's British newspaper  subsidiary  News International. Democratic Senators Barbara Boxer, Jay Rockefeller, and Frank Lautenberg, called for the FBI to investigate  the day after News Corporation announced it was pulling out its $12 billion bid to take full control of British Sky Broadcasting, a British pay-for-TV outlet. John Fisher Burns, London bureau chief for our partner, The New York Times, explains the implications of Murdoch's latest move and whether it will be enough to contain the growing scandal.
