Rep. Jason Chaffetz (R-Utah) responded Monday on Twitter to reports and videos alleging a six-year-old had been inappropriately searched at the Salt Lake City airport.
The reports, which included video footage of the incident, led the "Drudge Report" for most of the day.
"I am preparing a letter to the Obama administration demanding an investigation," Chaffetz tweeted.
He noted he also wanted details on the "apparent harassment" of the college student, Luke Tait, who took the video. Tait told reporters Monday that he was pressured by TSA employees to delete the recording from his phone.
