WASHINGTON (AP) — The extramarital affair that brought down David Petraeus' celebrated career last week raised many questions. Among them: when exactly the affair began, how the FBI stumbled upon the information and who was told about it. Here's a timeline of events, according to officials involved in the investigation:
Spring 2006 — Paula Broadwell meets Petraeus at Harvard University where she is a graduate student. Petraeus is a lieutenant general working on a manual about counterinsurgency and is invited to give a speech about his experiences in Iraq.
January 2007 — The Senate confirms Petraeus as the commanding general for U.S. troops in Iraq.
2008 — Broadwell initiates a case study of Petraeus' leadership. On a visit to Washington, Petraeus invites Broadwell to join him and his team for a run along the Potomac River.
October 2008 — Petraeus is named commander of U.S. Central Command, based at MacDill Air Force Base near Tampa, Fla., where Jill Kelley and her husband attend social events alongside the area's military elite.
June 30, 2010 — The Senate confirms Petraeus as the new commander for war in Afghanistan. Over the next year, Broadwell expands her research of Petraeus into an authorized biography. She makes multiple trips to Afghanistan and is given unprecedented access to Petraeus and his commanders.
Sept. 6, 2011 — Petraeus is sworn in as CIA director with his wife, Holly, by his side. Broadwell keeps in contact with Petraeus and is later invited to his office for events, including a meeting with actress Angelina Jolie.

Jan. 30, 2012 — In an interview with her hometown paper, the Bismarck Tribune, Broadwell describes Petraeus as an inspirational figure who always takes care of his subordinates.
May 2012 — Kelley, a Tampa socialite, starts receiving harassing emails. The FBI begins investigating soon after.
Summer 2012 — FBI agents determine that the email trail leads to Broadwell. They come across a private Gmail account using an alias name that belongs to Petraeus. Emails between Petraeus and Broadwell lead agents to believe the two are having an affair. FBI Director Robert Mueller is notified. At some point during the investigation, the FBI interviews Petraeus and Broadwell.
