WASHINGTON, D.C. -- The TSA's recent decision to soon allow small knives back on airplanes for the first time since the deadly 9/11 terror attacks is facing a new challenge on Capitol Hill.
The issue is around blades smaller than 2-and-a-half inches. The TSA says they pose little threat, and Chief John Pistole says the objects distract screeners from the real terrorism threat, explosives.
"That's their focus, and so that's where we focus our efforts," Pistole said, describing the TSA's focus on the knives.
However, a growing number of people from airlines, to flight attendants -- even passengers -- see it differently.
David Cox is with the American Federation of Gov't Employees. Cox says the threat from these small knives is real.
"Two inches of a knife can literally kill someone. We know that," Cox said.
The controversy has caught the attention of lawmakers.
Massachusetts Representative Ed Markey introduced a bipartisan "No Knives Act" this week, freezing the list of permitted carry on items. On Thursday, he'll be joined by flight attendant unions protesting the TSA representing at least three major airlines. Under Markey's act, the TSA's knives policy would change April 25th.
