Last November former Army General and Director of the CIA David Petraeus resigned after a cheating scandal broke. The FBI then launched an investigation into Petraeus believeing he let his former lover handle classified CIA documents. On Friday the FBI headed to Petraeus' Northern Virginia home to interview the former General.

While in the Petraeus home the FBI interviewed him about the allegations Petraeus allowed his mistress to handle and look at classified CIA documents. Petraeus was having an affair with his biographer Paula Broadwell, an Army Reserve intelligence officer. Both Petraeus and Broadwell were married when they carried on their relationship.

The FBI removed documents from the Petraeus' North Carolina home back in November as part of the initial investigation. When the General resigned those who followed Petraeus' career were shocked. They expected Petraeus to end his career in the White House not being investigated by the FBI.

According to the Christian Science Monitor, "Petraeus was credited with helping pull Iraq from the brink of all-out civil war as commander there and President Barack Obama turned to him to lead U.S. forces in Afghanistan before moving to him to the CIA in 2011."

In separate interviews conducted by the FBI both Petraeus and Broadwell denied that she had ever handled classified CIA documents.

The FBI investigation into Petraeus is still ongoing. It is not clear what evidence the FBI has gathered. Petraeus declined to make a statement when contacted by various media outlets.
