Union sues feds over hack, says agency had ample warning

The largest federal employee union filed a class action lawsuit Monday against the federal personnel office, its leaders and one of its contractors, arguing that negligence contributed to what government officials are calling one of the most damaging cyberthefts in U.S. history.

The suit by the American Federation of Government Employees names the Office of Personnel Management, its director, Katherine Archuleta, and its chief information officer, Donna Seymour. It also names Keypoint Government Solutions, an OPM contractor.
