Washington (CNN) - Sen. Jay Rockefeller, the Democratic chair of the Senate Commerce Committee, told CNN Wednesday he is considering an investigation into whether News Corp employees broke the law by hacking U.S. citizens.
"My bet is we'll find some criminal stuff," Rockefeller said. "This is going to be a huge issue," he said as he was leaving the Senate chamber after a vote.
"We'll have jurisdiction over that. If it's criminal it moves to the judiciary."
Rockefeller declined to provide specifics to back up his suspicions.
A Rockefeller aide said the senator thinks News Corp journalists here in the United States or in the United Kingdom might have targeted U.S. citizens.
On Tuesday night, Rockefeller issued a statement urging "appropriate agencies to investigate to ensure that Americans have not had their privacy violated" by journalists working for the company.
In his statement, he said the allegations "raise serious questions about whether the company has broken U.S. law." Rockefeller said he was particularly concerned 9/11 victims may have been hacked.
But his comments Wednesday went a step further, with the powerful chair of the committee that oversees large aspects of the U.S. economy saying he believes the company's actions may have been criminal.
