Rep. Hank Johnson (D-Ga.) told Credit Union Times that Congress should hold hearings to investigate the Target security breach.

"Yeah, I do think an airing of what occurred is important for Congress to understand and to be able to adjust any laws that may be applicable so as to either get at or alleviate that threat. The American people also need to know the extent of the breach and the ramifications of it," Johnson told Credit Union Times this week on Capitol Hill.

"If we simply rely on the company investigation to gather all the facts and then disseminate it to the public, that may not be as clean and thorough and valuable to the public, to the victims, as it should be. So, I would support an oversight investigatory hearing to probe into that matter," he added.
