MIAMI (CBSMiami/AP) – The FBI investigation into former CIA chief David Petraeus, which uncovered his affair with his biographer Paula Broadwell, reportedly began after Broadwell allegedly sent harassing emails to a woman in Tampa.
That's according to a senior military official was not authorized to discuss the case publicly and spoke on the condition of anonymity.
The FBI probe began several months ago with a complaint by 37-year old Jill Kelley, a State Department's liaison to the military's Joint Special Operations Command, against Broadwell. That investigation led to Broadwell's email account, which allegedly revealed the relationship with Petraeus, according to the military official.
Another person who knows Kelley and Petraeus confirmed their friendship and said she saw him often.
Petraeus quit as CIA director last Friday acknowledging an extramarital relationship with a woman later identified as Broadwell.
Broadwell is a research associate at Harvard's Center for Public Leadership and a Ph.D. candidate in the Department of War Studies at King's College London, according to her biography on Penguin's website. According to The Bismarck (N.D.) Tribune, she grew up in North Dakota and moved to Charlotte, North Carolina more than three years ago with her husband, a radiologist, and their two young sons.
Broadwell first met fellow West Point graduate Petraeus in the spring of 2006, when she was a graduate student at Harvard's Kennedy School of Government.
He was a lieutenant general working on a counterinsurgency manual that would be tested during his command in Iraq. The university had invited him to give a speech.
Broadwell was in the Army Reserve after being recalled three times to active duty since the Sept. 11 attacks to work on counterterrorism issues and intended to return to active duty or get into the policy world, according to the preface of the Petraeus biography she would later write with a Washington Post editor.
Broadwell wrote in the preface to "All In: The Education of General David Petraeus," published by Penguin in January, that while at Harvard, Petraeus passed along his card and offered to help her academic work on leadership.
"I later discovered that he was famous for this type of mentoring and networking, especially with aspiring soldier-scholars," Broadwell wrote, adding that "I took full advantage of his open-door policy to seek insight and share perspectives."
