I think Rep. Tuck is wrong to claim that literally no regulation exists requiring us to present ID to TSA before it will allow us to access an airport's boarding gates. There is such a regulation, but the regulation is not published because it is "sensitive security information" under federal law. It's a secret regulation. (Ask Don, Lisa, or Dan if they think secret regs are OK, but for now it's totally legal and constitutional.) The secret reg requires a valid ID, or submission to "additional screening", i.e. interrogation and pervy groping. So, you do not NEED an ID in the sense that you can choose the pervy groping.
