Yesterday, Truth in Media brought news of a Department of Homeland Security report, first published by ABC News, which identified the fact that the Transportation Security Administration utterly failed a DHS security test in which undercover “red team” agents posed as passengers and attempted to slip through checkpoints at US airports carrying potential weapons or explosives. Over the course of the test, TSA agents allowed 67 out of 70 armed undercover agents to slip through checkpoints at dozens of American airports, raising questions about the bureau’s ability to protect airline passengers.

Late Monday afternoon, Department of Homeland Security Secretary Jeh Johnson ordered a series of changes aimed at fixing the security vulnerabilities. Fox News notes that Secretary Johnson has reassigned TSA Acting Administrator Melvin Carraway to work in the DHS Office of State and Local Law Enforcement and has promoted Acting Deputy Director Mark Hatfield to Carraway’s former position as TSA Acting Administrator.

“We take these findings very seriously. The numbers in these reports never look good out of context, but they are a critical element in the continual evolution of our aviation security,” read a statement by Department of Homeland Security Secretary Jeh Johnson.

Additionally, Secretary Johnson ordered a review of the agency’s screening equipment and that TSA officers undergo extra training. He also plans to continue the undercover testing program.

Former White House counter-terrorism official Frank Cilluffo told CBS This Morning in the above-embedded video that, when it comes to security, “We’ve got to be right 100% of the time. The adversary only has to be right once.”

According to The New York Times, President Obama nominated Coast Guard Vice Admiral Peter Neffenger to serve as TSA Administrator back in April, but Neffenger has yet to be confirmed by the Senate. Secretary Johnson called on senators to confirm Neffenger in the wake of the failed tests.

An aide to Senate Homeland Security Committee Chairman Ron Johnson (R-WI) told Fox News that the test’s findings that have been published so far in news reports “raise valid concerns in light of earlier inspector general findings and ‘red team’ tests of TSA’s vulnerabilities.” Said Senator Johnson’s aide, “Taxpayers have spent billions of dollars to secure our air travel system. It’s important for that goal to be met.“
