JACKSON, Miss. — Former Mississippi Gov. Haley Barbour says it was “nobody’s fault but mine” that he took a loaded handgun in his briefcase through an airport security checkpoint in early January.

Barbour said Tuesday he will pay a fine after he was stopped and arrested Jan. 2 while boarding a flight from Mississippi to Washington, D.C. The gun was spotted in a TSA X-ray machine.

He says he forgot he was carrying the gun, which he had put in his briefcase after an assistant removed it from his car days earlier.

Transportation Security Administration spokeswoman Lisa Farbstein says a TSA officer working at an X-ray machine at a checkpoint at Jackson-Medgar Wiley Evers International Airport spotted a .38-caliber revolver, loaded with five bullets, in a passenger’s carry-on bag.

The TSA confiscated this revolver from a passenger on January 2, 2018, at Jackson-Medgar Wiley Evers International Airport in Jackson, Mississippi. TSA wouldn’t release the name of the passenger, but confirmed it was a former governor. Haley Barbour later confirmed he was the passenger (TSA via AP)
