WASHINGTON (AP) - His spokesman says President Barack Obama "thinks very highly" of Gen. John Allen.
But Allen's nomination to head U.S. European Command and be the commander of NATO forces in Europe is on hold, as investigators examine thousands of pages of documents and emails between Allen and a Florida woman, Jill Kelley.
A senior defense official describes some of the messages as "flirtatious."
Kelley is the woman who received threatening emails from Paula Broadwell, who'd been having an affair with then-CIA Director David Petraeus. Those emails led investigators to uncover the affair, which forced Petraeus to resign.
One leading House lawmaker says the latest revelations are "a Greek tragedy." Peter King tells NBC that it sounds like "a Hollywood movie or a trashy novel."
The FBI is preparing a timeline for Congress about the investigation that led to the discovery of the affair involving Petraeus. Some lawmakers have said they should have been told about it earlier.
The White House wasn't informed about the FBI investigation until Election Day, although agents began investigating Petraeus months earlier.
