WHITFIELD: All right, a reaction now from lawmakers about that massive computer hack of the U.S. Government, 4 million former and current federal employees' personal information now at risk. Well today lawmakers warn the breach could really be about China laying the groundwork for an expanded cyber attack against the U.S. Sunlen Serfaty joining us now from Washington with more on the reaction, Sunlen.</s>SUNLEN SERFATY, CNN NATIONAL CORRESPONDENT: Well Fred, the chairman of the house homeland security committee -- he is sounding you the alarms, warning that he believes all of this stolen information could be used for blackmail or for recruitment for spies. Here's Representative McCaul on "Face The Nation."</s>REP. MICHAEL MCCAUL (R), TEXAS: It was not done to steal credit card information and that kind of theft. It was done to get personal information on political appointees in the federal government and federal employees to exploit them so that later down the road, they can use those for espionage to either recruit spice or compromise individuals in the federal government.</s>SERFATY: The President's attending the G7 Summit in Germany and today, his press secretary said the U.S. is considering ways to punish whatever person or government was involved in this breach.</s>JOSH EARNEST, WHITE HOUSE PRESS SECRETARY: Our investigators are still looking into who precisely carried out these intrusions. The option that the President put on the table for responding to these kinds of activities in the form of financial sanctions certainly is one that continues to be available to him and the administration with regard to this particular activity.</s>SERFATY: The White House is not officially laying blame on who was behind this but sources say U.S. investigators do believe they can track the breach to the Chinese government. Chinese officials, Fred, have denied that they are behind this.</s>WHITFIELD: All right, Sunlen Serfaty thank you so much in Washington. We will be right back after this.
