TAMPA, Fla. (AP) — CIA Director David Petraeus was shocked to learn last summer that his mistress was suspected of sending threatening emails warning another woman to stay away from him, former staff members and friends told The Associated Press Monday. Petraeus told these associates his relationship with the second woman, Tampa socialite Jill Kelley, was platonic, though his biographer-turned-lover Paula Broadwell apparently saw her as a romantic rival. Retired Gen. Petraeus also denied to these associates that he had given Broadwell any of the sensitive military information alleged to have been found on her computer, saying anything she had must have been provided by other commanders during reporting trips to Afghanistan.
