The Transportation Security Administration will add 768 new screeners by mid-June to deal with increasingly long airport security lines that have caused passengers to miss flights even before the busy summer travel season, the agency's chief told Congress on Wednesday. Most of the new screeners will be sent to the nation's busiest airports in Chicago, New York, Atlanta, Los Angeles and other hubs. (AP Photo/Seth Wenig), APTOPIX
