President Obama “has faith” in General Allen’s ability to lead the International Security Assistance Force,” but he wants the Senate to confirm his successor as quickly as possible and hasn’t spoken to Allen since the Pentagon began investigating Allen’s relationship with a woman involved in the David Petraeus scandal.

“I can tell you that the president thinks very highly of General Allen and his service to his country as well as the job he has done in Afghanistan,” White House Press Secretary Jay Carney told reporters today. “He has faith in General Allen [and] believes he is doing and has done an excellent job at ISAF.”

Carney said that Obama had not spoken with Allen — “Not that I’m aware of, no ” he said — and recommended that reporters talk to the Pentagon for further information about the investigation into Allen.

“According to a senior U.S. defense official, the FBI has uncovered between 20,000 and 30,000 pages of documents — most of them e-mails — that contain “potentially inappropriate” communication between Allen and Jill Kelley, the 37-year-old Tampa woman whose report of harassment by a person who turned out to be Petraeus’s mistress ultimately led to Petraeus’s downfall,” The Washington Post reported today.

Carney didn’t have much to say about why the White House didn’t know before the election about the investigation that brought down Petraeus, even though Attorney General Eric Holder reportedly knew.

“The FBI is the place to go for the protocols they follow,” he said.
