The Obama administration is scrambling to assess the impact of a massive data breach involving the agency that handles security clearances and employee records, U.S. officials said Thursday.
A congressional aide familiar with the situation, who declined to be named because he was not authorized to discuss it, said the Office of Personnel Management and the Interior Department were hacked. A second U.S. official who also declined to be identified said the data breach could potentially affect every federal agency.
The White House was considering a public announcement of the breach Thursday night or Friday morning, the second official said.
The Office of Personnel Management is the human resources department for the federal government, and issues security clearances.
In November, a former Department of Homeland Security official disclosed another cyberbreach that compromised the private files of more than 25,000 DHS workers and thousands of other federal employees.
