Lindsey Graham blames President Obama for data breach

Updated

The White House was scrambling Thursday to assess the impact of a massive data breach, suspected to have originated in China, involving the agency that handles security clearances and employee records, according to U.S. officials. So far, they said, the breach doesn’t appear to be the “worst-case scenario” — compromise and disclosure of the identities of the covert CIA agents.
