Undercover Homeland Security investigators trying to sneak mock knives, guns and explosives past TSA agents at airports reportedly were successful around third-quarters of the time, according to multiple reports of a classified briefing that was given to a House committee.
TSA announced last month that all flights arriving to the United States would be subjected to new security screening procedures, with American citizens as well as foreigners possibly facing interviews by airline employees.
Twitter users questioned whether airports should still use TSA and lamented the security process.
Undercover operatives from the Department of Homeland Security's Office of Inspector General (OIG) were able to smuggle contraband through USA airports at a high rate, according to a new report shared with a Congressional committee.
The latest tests come just two years after the DHS secretly audited the agency and found that it failed 95 percent of the time.
ABC News first reported inspectors' findings and while the exact rate of failure has not yet been released to the public, when asked if the number was somewhere around 80 percent, an unnamed source replied, "You are in the ballpark".More news: TCU shuttle driver arrested after gunshot fired, road rage incident on campus

"We found that briefing disturbing", House Committee on Homeland Security Chairman Rep. Michael McCaul, R-Texas, said at a hearing following Wednesday's briefing to discuss the details of the tests conducted by Office of the Inspector General.
The Department of Homeland Security has since offered eight recommendations to improve checkpoint security.
New equipment available would create 3D images of luggage to help screeners spot risky items, but it's only in use at two airports so far.
During the hearing, U.S. Rep. Mike Rogers told TSA Administrator David Pekoske that his agency "is broken badly, and it needs your attention".
In a statement, the TSA said they take the findings very seriously and are implementing measures that will improve screening and effectiveness at checkpoints.
