David Petraeus Affair Reveals Threatening Letters From Mistress To Another Woman

The woman who blew the whistle on the David Petraeus affair says she received threatening emails from the mistress. INSIDE EDITION has the latest.

The first video has surfaced of the woman who blew the whistle on the sex scandal that ended the brilliant career of CIA Director David Petraeus. 

Jill Kelley ignored questions as she left her home in Tampa, Florida, this morning. She's the so-called "other, other woman" on the receiving end of those threatening and harrassing emails from Paula Broadwell.

The emails reportedly warned Kelley to "back off" and "stay away from my guy."

And there was this: "I know what you did."

CBS News Homeland Security Correspondent Bob Orr said, "The sudden downfall of CIA Director David Petraeus was rooted in jealousy."

A photo has surfaced of 37-year-old Jill Kelley with Petraeus' wife, Holly, her husband, Scott, Petraeus himself.

Kelley says her relationship with Petraeus was purely platonic and her family says in a statement:

"We and our family have been friends with General Petraeus and his family for over five years. We respect his and his family's privacy, and want the same for us and our three children." (Source: Kelley family)

Meanwhile, we're learning more about Paula Broadwell, who wrote a fawning biography of him, All In, The Education of General David Petraeus.

She's a fitness fanatic who showed who showed off her toned arms and won a push-up contest against The Daily Show's Jon Stewart.

Stewart asked, "Is he awesome, or incredibly awesome?"

"He can turn water into bottled water," said Broadwell.

The other guy doing push-ups on the show with them was her doctor husband, Scott, a radiologist.  They're the parents of two young boys. And get this, they live in the same ritzy suburb of Charlotte, North Carolina, as Rielle Hunter, the one-time mistress of former presidential candidate John Edwards.

In the driveway of Broadwell's home, a note written in chalk reads: "Dad Loves Mom."

Broadwell was a high-achiever since high school in Bismarck, North Dakota. She was Homecoming Queen, and went on to graduate from West Point. She retired from the army with the rank of Major.

Broadwell was recently featured in a promotional video for a manufacturer of 45-caliber machine guns. She travelled extensively with General Petraeus when he was commanding U.S. forces in Afghanistan following his widely praised role in Iraq.

Newt Gingrich said on The View, "He is a brilliant and very hard-working person and I hope he and his family can work through this."

But Petraeus' aides reportedly complained that Broadwell wore tight outfits that were inappropriate for a war zone in a Muslim country.

Washington Post reporter Sari Horowitz said, "She was wearing clothes that were too tight for that part of the world in the Middle East and needed to be more sensitive about her clothing. And there is one report that Petraeus actually pulled in another supervisor who told her to stand down in terms of her clothing."
