Due to a recent data breach, Sen. Franken will be looking into Epsilon Data Management.

A data breach that allowed hackers access to the names and email addresses of consumers who do business with Target, Best Buy, TiVo and other Epsilon clients led Franken (D-Minn.) on Thursday to vow to "do more to protect Americans' digital information."

"This is one of the largest data breaches in history," said Franken, chairman of the Senate Judiciary Committee's new privacy panel.

"Yet most of the people affected by the Epsilon breach had never heard of that company before this week," he told POLITICO in a statement.

"We need to give Americans more awareness about who has their information and greater ability to protect it," Franken added. The breach "threatens the privacy of countless Minnesotans and has affected major Minnesota employers."

Franken said he wanted to explore these issues more as chairman of the new Subcommittee on Privacy, Technology and the Law.
