Eggleston has been asked “to look into what happened and report back to [McDonough] with recommendations on how the administration can improve processes and make sure something like this does not happen again,” said Caitlin Hayden, a spokeswoman for the National Security Council.

The move marks an effort by the White House to assure members of the U.S. intelligence community, as well as the public, that it regards the inadvertent disclosure as a security breach serious enough to warrant attention from high-level officials.

The exposure has been a source of embarrassment for the White House at a time when Obama has sought to focus attention on his efforts to bring an end to the war in Afghanistan. On Tuesday, Obama announced that he planned to reduce the U.S. presence there to 9,800 troops and formally end U.S. combat operations by the end of the year.
