The White House is remaining tight-lipped about its outing of the CIA's top spy in Afghanistan.

White House spokesman Jay Carney during a Thursday briefings with reporters said only that the matter is under investigation to “make sure something like this doesn't happen again.”

The White House mistakenly outed the CIA's station chief in Afghanistan during President Obama's surprise trip to the country over the weekend.

A White House press aide passed along to the media the name of the CIA's station chief in Kabul on a list of senior officials attending a military briefing for Obama during the trip. The aide reportedly received the list from the military.

Chief of Staff Denis McDonough has asked White House counsel Neil Eggleston to look into what happened and report back to him with recommendations on how the administration can improve its vetting process before giving the press manifests of individuals attending briefings with the president.

Carney repeatedly deflected questions about whether individuals responsible for exposing the station chief's identity will be held accountable.
