Around 9:45 Friday morning, there was a report of a foul odor near the Midwest Airlines' ticketing counter. Sheriff's spokesperson Kim Brooks says that a couple of Transportation Security Administration agents felt light-headed.
The fire department was called to investigate the cause of the odor. Milwaukee Fire Lt. Lawrence Jenkins says a hazardous-material team was responding to the scene. He says six people were affected, but wasn't sure if any lost consciousness.
Airport spokesperson Ryan McAdams tells FOX 6 that per normal procedure, the area was evacuated, but people are now slowly being let back into the area.
