The Transporation Security Agency is offering guidance on where Congressional offices can direct potentially upset constituents calling with complaints about its controversial new screening procedures.

In a letter, the TSA informs Congress that it has set up a TSA Contact Center which can be reached by e-mailing [email protected] or calling 1-866-289-9673.

The TSA is advising passengers to file complaints as soon as possible after the incident and include the airport, date, and time of travel and any other pertinent information. Complaints can be filed at the checkpoint. Travelers can also pass concerns to a TSA supervisor at the airport.

TSA has also set up a website for passengers looking for information on how to travel with special medication or with a disability at: http://www.tsa.gov/travelers/airtravel/specialneeds/index.shtm

TSA briefed House and Senate staff on the new procedures Monday and Tuesday.

The ACLU said they have received well over 600 complaints since TSA instituted the aggressive new screening and pat-down procedures on Oct. 28, and is considering whether to file a lawsuit.

"Complaints have just shot up since TSA changed to the more aggressive patdowns," the ACLU's Laura Murphy told POLITICO Tuesday.

Among the complaints they have received, Murphy said: "People feel like they are being touched in a sexually inappropriate fashion; they are citing lack of privacy, when their pants are being opened and TSA officers stick their fingers between the waistband and the skin. People who are victims of sexual abuse are complaining. ... People are feeling like they don't want the risk from radiation and some have vulnerable immune systems."

"There are concerns about children," Murphy said. "TSA has said that they are not putting kids under 12 through scanners. But if you have raised your child not to allow strangers to touch them," the TSA patdowns of the children concerns some parents. TSA until very recently "has not had an adequate complaint process."

The Electronic Privacy Information Center filed a lawsuit agaist the new TSA screening policies in D.C. Circuit court Nov. 1. citing health and privacy concerns and effectiveness.

"We have twice petitioned the agency to open this question up for comments, but they have been tone deaf," EPIC's Ginger McCall told POLITICO. "They are not hearing people's concerns."

With the TSA setting up a Contact Center to take passenger complaints, the Agency is showing signs of hearing people's concerns a bit more, if not yet changing the controversial policies over the high-travel Thanksgiving holiday. A new Washington Post/ABC poll Monday showed 51% of the American public opposes the aggressive new pat-down procedures, while 64% support the use of the scanner machines.
