Jean Weber said her mother was being patted down before boarding a plane to Michigan when the agent said the diaper felt strange and had to be removed.
"She was very calm. She can't hear well. If they were explaining things to her, I do not know if they were able to make her understand or not," she said. "She was calm through it all, and she was upset about not being able to have any underwear on, and I said, 'I don't know what else to do Mom, I really don't.'"
The agency said in a statement that the officers "acted professionally and according to proper procedure."
The Transportation Security Administration has come under fire for its pat downs and security screening process. Just recently, it changed its policy for children.
Under the new plan, kids age 10 and under will only be patted down as a last resort after agents have made repeated attempts at other screening methods.
