TAMPA, Fla. (AP) - 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.
 
Today, the 47-year-old agent finds himself in the middle of the widening scandal that has resulted in CIA Director David Petraeus' resignation.
 
Humphries was the agent who initially saw the emails the FBI said Petraeus' biographer and mistress, Paula Broadwell, sent to Tampa socialite Jill Kelley, a woman she apparently saw as a rival for Petraeus' affections. She also allegedly sent emails to Gen. John Allen, Kelley's friend and the top U.S. commander in Afghanistan.
