Ever since his scandalous affair was revealed, forcing him to resign as head of the CIA, retired General David Petraeus has laid low.

He has slowly been rehabilitating both his career and reputation.

But now, he's about to start something new.

Chris Lawrence reports on what's next for Petraeus.

Paula Broadwell, the woman behind the relationship that led to the resignation of former CIA Director David Petraeus has become a tabloid sensation. The cover of this week's People magazine: "Sex, Lies and Spies."

But what do those who know her best say about what's happened? And what's her next move?

While the Petraeus scandal continues to unravel the FBI is probing into whether or not the numerous classified documents biographer, Paula Broadwell, obtained from the retired general's staff were authorized by Petraeus himself.

When Broadwell visited Petraeus in Afghanistan she would often ask for sensitive information she claimed Petraeus wanted her to be provided with, according to former staff members and officials.

FBI investigators are not only looking into what role staff members played in the release of this information, but are also inquiring if the classified material was provided when the former CIA director was in the military or when he resigned from the Army in September 2011 to head the CIA.

The CIA announced Thursday it's opening an exploratory investigation on the "general conduct" of former CIA Director David Petraeus.

Who knew what when and why wasn't the President told sooner about CIA Director David Petraeus' career ending affair with Paula Broadwell?

Today, Attorney General Eric Holder tried to explain.

"We felt very secure in the knowledge that a national security threat did not exist that warranted the sharing of that information with the White House or the Hill. But when we got to a point in the investigation, it was very late in the investigation, after a very critical interview occurred on the Friday before we made that disclosure – when we got to that point where we thought it was appropriate to share that information we did so," said Holder.

But was there in fact a threat to national security? And why wasn't the President informed of the investigation - which began in the summer - before last week?
