The phone-hacking scandal that has rocked Rupert Murdoch’s media empire is expanding on U.S. soil. Lawyer Mark Lewis, who helped expose the massive scandal in Britain, said he is partnering with U.S. lawyer Norman Siegel, who has been investigating the possible hacking of 9/11 victims’ cellphones by the British tabloid News of the World. While Lewis said many complaints against News Corp. in the United States stem from the now-defunct tabloid, he also said there have been initial allegations against Fox News and other News Corp. holdings. Lewis said he is now representing four clients who believe their phones were hacked while visiting the United States.

Mark Lewis: “What they’re alleging is that they either left messages or received messages and that their messages were therefore listened into or investigations were sourced. See, what you have to understand is, if one person is speaking to another person, the very fact that they’re even speaking to each other is potentially news. You know, if you have somebody who is having an adulterous relationship with another person, the very fact that they’re speaking to each other is what you, as a journalist, if you’re writing about a relationship, is what you need as a primary source or a secondary source. It doesn’t really matter what they say.”
