Those security scanners are being tested at six airports across the country, including at Salt Lake International Airport.
Chaffetz says the images are extremely detailed, clearly showing a person's gender. He also says passengers expect privacy under their clothing and shouldn't be required to display personal parts of their bodies before boarding an airplane.
Representative Chaffetz says "Nobody needs to see my wife and kids naked to secure an airplane". Chaffetz also has an issue with the cost of the scanners, they are $170,000 a piece. He says originally they were meant for secondary screening devices.
But now, TSA has stated the plan is now for all passengers to go through them instead of the walk-through metal detectors.
