WASHINGTON (AP) -- The sex scandal that's claimed the career of CIA Director David Petraeus has gotten wider.
President Barack Obama has put on hold the nomination of the top U.S. commander in Afghanistan, Gen. John Allen, to become the next commander of U.S. European Command as well as NATO supreme allied commander.
Investigators have uncovered 20,000-plus pages of documents and emails involving Allen and Tampa socialite Jill Kelley, some of which was described as "flirtatious" in nature.
It was Kelley, a close friend of Petraeus, who triggered the FBI investigation that led to his downfall as CIA director. Kelley complained about getting anonymous, harassing emails that turned out to be written by Petraeus' biographer and mistress, Paula Broadwell, who was apparently jealous of Kelley.
Petraeus acknowledged the affair and resigned last week.
In the course of looking into that situation, federal investigators came across what a Pentagon official called "inappropriate communications" between Allen and Kelley, both of whom are married.
Allen insists he's done nothing wrong, and is working to salvage his career.
As for Kelley, she's been keeping a low profile at her home. At one point Tuesday, she left her house and ignored reporters' questions as she drove off.
Scandal causes commotion on the Hill
The unfolding scandal involving former CIA Director David Petraeus and Gen. John Allen is causing a commotion on Capitol Hill, where lawmakers complained that they should have been told about the investigation earlier.
Rep. Peter King, the chairman of the House Homeland Security Committee, calls the latest revelations "a Greek tragedy."
Acting CIA Director Michael Morell met with Senate Intelligence Committee Chairwoman Dianne Feinstein and ranking Republican Saxby Chambliss to explain the CIA's understanding of events that led Petraeus to resign. That session came ahead of meetings with the leaders of the House Intelligence Committee planned for Wednesday.
Asked by reporters if there was a national security breach with the Petraeus affair, Feinstein said: "We're going to hold an inquiry. We're going to look at things. I have no evidence that there was at this time." She said she expected Petraeus to testify.
Meanwhile, the chairman and top Republican on the Senate Armed Services Committee said their panel would go ahead with Thursday's scheduled confirmation hearing on the nomination of Marine Corps Gen. Joseph Dunford, who is to replace Allen as commander of U.S. and NATO forces in Afghanistan, if Allen is indeed promoted.
