QUEENS - A report released today shows an alarming number of security breaches at U.S. airports despite increased safety measures since the Sept. 11, 2001 attacks.

According to new government statistics, there have been more than 25,000 security breaches since Nov. 2011. Many travelers at La Guardia International Airport say the number is shocking.

Testifying at a hearing in Washington, D.C., Rep. Jason Chaffetz (R-Utah) said airports are still vulnerable to terror attacks even though the Transportation Security Administration (TSA) has made billions of dollars worth of security enhancements.

The TSA calls the statistic misleading and says it reflects not even 1 percent of the people who have been screened over the past 10 years. TSA officials also stress that the term "security breach" covers a wide range of incidents, from a misplaced checked bag to a person boarding a plane with a weapon.
