What was it, a couple of weeks ago that an illegal alien worker was found inside an Arizona nuclear power plant?
I also remember six or seven years ago at a Navy installation in San Diego, some contract workers were getting some training in working around radiological materials and a few hours into the class one of them mentioned they weren’t citizens.
Now all of the instructors have to asked at the beginning of class if everyone is a citizen.
Because we know a terrorist would never lie. /s
