The military has suspended the Air Force base pass of the Tampa socialite who sparked an ongoing sex scandal.

Pentagon spokesman Lt. Col. Steven Warren says the decision to indefinitely suspend Jill Kelley's pass to MacDill Air Force Base was made in the last couple of days.

Kelley's complaints about threatening emails triggered the FBI investigation that led to the resignation of CIA Director David Petraeus and a probe into communications between her and the top U.S. commander in Afghanistan.

Warren said it was decided the pass suspension would be in the best interest of the Air Force base community. Kelley can still enter the base but now must report to the visitor center and sign in like everyone who doesn't have a pass.

Meanwhile, we’re learning more about Kelley's twin sister, Natalie Khawam from her former employer, who said both women were proud of their military connections.

Tampa attorney Barry Cohen said when Khawam worked at his firm as an attorney she liked to talk about her "connections.”

"I often heard Natalie drop General Petraeus' name. She liked to take pictures at the house, show those pictures,” he said.

Cohen and Khawam are now involved in litigation but when they were on better terms, he said he attended parties at the Kelleys' house, describing Jill as a "great hostess."

"Very charming, very charismatic, very gracious,” he said.

FBI agent in Petraeus scandal connected to other well-known Tampa cases

The Tampa FBI agent who prompted the investigation that resulted in CIA Director David Petraeus' resignation is no stranger to the limelight.

FBI Special Agent Frederick Humphries II played a key role in stopping a terrorist attack aimed at blowing up Los Angeles International Airport just as the year 2000 dawned.

According to the Tampa Bay Times, Humphries was involved in the terrorism-related investigation of former University of South Florida student Youssef Megahed, who was acquitted in 2009 of federal explosives charges stemming from an arrest in South Carolina in 2007.

Humphries also fatally shot a man who threatened him and other law enforcement officers with a knife during an altercation at Tampa's MacDill Air Force Base in 2010.

Humphries was the agent who initially saw the emails Petraeus' biographer, Paula Broadwell, sent to Tampa socialite Jill Kelley. Humphries thought the emails raised serious concerns because the anonymous author knew the comings and goings of Petraeus and Gen. John Allen, the top U.S. commander in Afghanistan.
