Dreeben laid out for Cobb one way the White House could cooperate. He cited a 2008 opinion under Attorney General Michael Mukasey that found the White House could share sensitive internal documents with another executive branch office, such as the Justice Department, for the purposes of an investigation. As Dreeben explained, the White House wouldn’t have to deal with the question of whether these records should be shielded by executive privilege because under the Mukasey memo the executive branch would agree not to divulge any of the records without White House permission.
