Investigators say data breaches at the U.S. government's personnel management agency involves millions more people than previously estimated. Vanessa Johnston reports.
When a government agency was hit by a massive hack months ago....at OPM, or the Office of Personnel Management... Officials estimated that some 4 million people had had their personal data stolen -- including Social Security numbers. Now investigators are putting that number at 21.5 million. They include current, former, and prospective employees and their significant others -- All of whom underwent background checks for security clearances. U.S. officials have named China as the leading suspect. China has dismissed the claim as "absurd logic". Lawmakers from both parties are now demanding the removal of OPM Director, Katherine Archuleta. But the White House says President Obama still has confidence in her leadership.
