Investigation: Undercover agents snuck fake explosives, banned weapons past TSA Published June 01, 2015 FoxNews.com
The findings were part of a DHS inspector general probe. The report is still classified, but Fox News has confirmed the investigation found security failures at dozens of airports.
Homeland Security officials confirmed to Fox News that TSA screeners failed 67 out of 70 tests -- or 96 percent -- carried out by special investigators known as "red teams."
In one case, an undercover agent with a fake bomb strapped to his back set off a magnetometer -- but the screener still failed to find it.
