Two lawmakers want the U.S. Justice Department to investigate whether employers who require job applicants to hand over confidential passwords to Facebook and other social networking sites are violating federal law. Sen. Charles Schumer of New York and Sen. Richard Blumenthal of Connecticut said they also will ask the U.S. Equal Employment Opportunity Commission to examine the practice. Facebook Inc.has described as “alarming” reports that some businesses ask potential employees for passwords in order to view private posts and pictures as part of the job-application process. The two lawmakers said the practice could violate federal anti-hacking statutes.
