Petraeus Affair: A Comprehensive Update

Nov. 13, 2012 -- What started as Gen. David Petraeus' surprise resignation from his post as CIA director has ballooned into a full-fledged scandal, implicating his successor general in Afghanistan, his biographer, the FBI and a whole family of military supporters. Here's a rundown of what we've learned of late:

A Second Afghanistan General Is Under Investigation

Gen. John Allen, the commander of American forces in Afghanistan, came under investigation because of 20,000 to 30,000 emails connecting him to Jill Kelley, the Tampa military enthusiast who received what she perceived as a harassing email from Petraeus' biographer-turned-mistress, Paula Broadwell. A Defense Department official characterized some of those emails as "inappropriate" and "flirtatious," but another official said they were mostly harmless, and there were likely no sordid interactions between Allen and Kelley.

White House Press Secretary Jay Carney told reporters today that President Obama stands by Gen. Allen. The president accepted Petraeus' resignation last week, but he continues to have "faith" in Allen, Carney said.

Petraeus Personally Investigated Benghazi

In late October, Petraeus traveled to Libya to conduct his own review of the Benghazi attack that killed four Americans, including U.S. Ambassador Christopher Stevens.

The Libya stop was part of a six nation trip to the region. Petraeus intended the review as a way to prepare for his upcoming testimony before Congress on Benghazi.

ABC's Sunlen Miller reports that Republican Sen. Susan Collins of Maine and other law makers say it's "imperative" that Petraeus still give that testimony.

Sen. Dianne Feinstein, chairwoman of the Senate Intelligence Committee, expects the Senate will need to hear from Petraeus on the Libya attack "one way or another."

All About the Kelleys

Jill Kelley, 37, is a Tampa socialite who volunteered her time to support the military, planned and hosted charitable events and forged tight friendships with top brass. Her sister Natalie also became friendly with major players, including both Gen. Petraeus and Gen. John Allen, commander of the International Security Assistance Force in Afghanistan, who wrote letters on her behalf as she battled her ex-husband for custody of her son.

Kelley's social efforts on behalf of the military earned her the unpaid title of "honorary ambassador" to CENTCOM, the Defense Department's Central Command, which is based in Tampa at MacDill Air Force Base and has responsibility for directing operations in Iraq and Afghanistan.

ABC News' Steven Portnoy reports the special license plate designating Jill Kelley as an "Honorary Consul," on her gray Mercedes Benz S500 is not just because she was considered CENTCOM's "social ambassador."

A staffer at the Embassy of Korea in Washington confirms that his government conferred "honorary consul" status upon Kelley in August of this year.
