WASHINGTON  — Retired Gen. David Petraeus began an affair with his biographer in 2011, two months after he became CIA director, a friend and former top aide said. The case has brewed an uproar in Congress over FBI investigative tactics and the fact lawmakers weren’t told soon enough about the probe rocking the intelligence and law enforcement establishment.

Petraeus, who resigned last week as the nation’s head spy, and his family are said to be devastated over the affair, especially his wife Holly, who “is not exactly pleased right now,” said Steve Boylan, a friend and former Petraeus spokesman who spoke to Petraeus over the weekend.

Petraeus, 60, quit Friday after acknowledging the affair. He has been married 38 years to Holly Petraeus, with whom he has two adult children, including a son who led an infantry platoon in Afghanistan as an Army lieutenant.

Broadwell, a 40-year-old graduate of the U.S. Military Academy and an Army Reserve officer, is married with two young sons.

Meanwhile, information has emerged about a Florida woman who allegedly received harassing emails from Broadwell which led federal investigators to discover Petraeus’ sexual indiscretion with Broadwell.

A senior U.S. military official identified the second woman as Jill Kelley, 37, who lives in Tampa, and serves as an unpaid social liaison to MacDill Air Force Base in Tampa, where the military’s Central Command and Special Operations Command are located. Staffers for Petraeus said Kelley and her husband were regular guests at events he held at Central Command headquarters.
