VIDEO: Quite the odd situation as several TSA workers were taken to the hospital after falling ill.
It's left a lot of questions, and officials don't have any answers at the moment.
The security workers reportedly fell ill while working at a CWA checkpoint.
Firefighters responded taking 5 people to the hospital.
Then they tested the area for chemical exposure.
"So the first initial call was for one patient which is why we came with just the one ambulance to begin with, and as soon as I realized that there may be something else going on we kind of moved everybody out, paged the fire department to come in so that they have the, you know the protective equipment required to go into an unknown atmosphere and they were able to go in with the gas detectors," said Adam Grahn Mosinee Fire Chief.
