WASHINGTON (AP) - A union representative for police officers that secure Los Angeles International Airport says he still has concerns about a manpower shortage and a lack of coordination and communication with the Transportation Security Administration nearly seven months after a gunman killed a TSA officer and injured three others.

WASHINGTON (AP) A union representative for police officers that secure Los Angeles International Airport says he still has concerns about a manpower shortage and a lack of coordination and communication with the Transportation Security Administration nearly seven months after a gunman killed a TSA officer and injured three others.

Marshall McClain told a House subcommittee Thursday the airport has been increasing its size and passenger levels, but the number of "sworn officers" responsible for helping secure the airport has steadily declined in recent years.

A subcommittee with oversight over transportation security called on McClain and other airport security officials to discuss lessons learned from the Nov. 1 shooting.

McClain says lawmakers should urge airports receiving substantial federal money to station more local police officers in screening areas.
