...Does she not travel as a regular American when in USA ? It is not as if frisking is only for ordinary mortals and not for American-RAPE class.
Nowadays they frisk all and sundry even in US Airports ...
Most already know this but
no, not all are treated same when they go through US Airports. Many can (and do) get, for example Global Entry Permit which speeds up these things. If you travel frequently this is something to consider. (Those family members, who travel a lot have it, and it really speeds up the custom/security etc ...for example, you don't have to remove your shoes, or take out your laptop, and thus sometimes can save literally an hour or so.as you also have a much shorter queue)
( For those who are interested, any one (or your employer some time because it costs money) can apply. It is a program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States.
At airports one goes to Global Entry kiosks, presents machine-readable passport (or even a Green card, I think), places one's fingertips on the scanner, make a customs declaration. The kiosk issues the traveler a transaction receipt and directs the traveler to baggage claim and the exit. - Of course, one has to be pre-approved and undergoes a rigorous background check).
Of course, some rouge TSA officer can still be a jerk, (as they can still select someone for further examination), like it happened to an Indian ambassador, or an US congressman and it becomes a big scandal. (At present US law does not provide enough accountability against the rogue TSA, and they get away from punishment even when they mistreat a high positioned US person as they (TSA) get immunity, and so sometimes arrogant enough to disregard even the local police.
