Official: Screening will be minimally invasive

The head of the federal agency responsible for airport security says screening procedures should be as minimally invasive as possible, shifting his position that there would be no change in controversial scans and pat-downs.

The head of the Transportation Security Administration, John Pistole, said in a statement Sunday afternoon that the agency is constantly evaluating and adapting security measures and there is a continual process of refinement and adjustment to ensure air safety. (AP)
