Head of TSA security operations removed from position

"Kelly Hoggan has been removed from his position as head of security at TSA," the House Committee on Oversight and Government Reform posted on Twitter.

About a year later, a report from the Homeland Security Inspector General's office revealed that agency employees failed to find explosives, weapons and other dangerous items in more than 95 percent of covert tests at multiple U.S. airports.

Neffenger has also attributed some security line woes to fewer people than anticipated applying for the government's PreCheck program, which allows passengers to move through security faster after submitting to a background check.
