"I am so furious with them I can't even see straight," Chaffetz said Thursday. "They should not be taking minors by themselves for pat downs."
The new legislation would make it so that TSA can't pat down a minor unless a parent gives consent and is present for the screening. If a minor is traveling alone, a representative of an air carrier must supervise the pat down.
Chaffetz also sent a letter to TSA Administrator John Pistole on Wednesday after a video surfaced showing a 6-year-old girl being frisked by agents despite a protest from her mother.
"The agency must get serious about the manner in which it seeks to balance national security with personal privacy," Chaffetz wrote to Pistole in requesting a report on the incident. "At the very least, it cannot continue to operate under the belief that little girls and handicapped children pose such a serious threat that [agents] must abandon all manner of decency when interacting with them."
TSA spokeswoman Carrie Harmon said the agency doesn't comment on pending legislation.
As for the incident with the 6-year-old girl, the agency says it reviewed the screening and determined that the officer followed the correct procedure. But the agency adds that it is reviewing its "one size fits all" system for low-risk travelers such as young children and may make changes.
Chaffetz has introduced legislation to bar whole-body imaging machines, which can peer through travelers' clothes, as primary screening tools and has been a constant critic of the agency.
The congressman had his own run-in with TSA in 2008, when he refused to go through a body-imaging machine and then complained about an aggressive pat down.
