The practice of "ghosting" first achieved widespread attention in 2005 when the "Washington Post" broke a story suggesting that the U.S. Army and the CIA were detaining "unlawful enemy combatants" at the Abu Ghraib prison in Iraq with little or no due process. According to the article, the CIA asked military intelligence officials to let them house ghost detainees at Abu Ghraib by September 2003 and proposed a Memorandum of Understanding between the agencies on the topic that November. The Army and the Defense Department have acknowledged that the United States has used ghosting in the past, but have said it was limited to isolated incidents. According to documents obtained by the "Post", "unregistered CIA detainees were brought to Abu Ghraib several times a week in late 2003."
