Journalists including Jane Mayer, Joby Warrick and Peter Finn, and Alex Koppelman have reported the CIA was already using these harsh tactics before the memo authorizing their use was written, and that it was used to provide after-the-fact legal support for harsh interrogation techniques. A Department of Justice 2009 report regarding prisoner abuses reportedly stated the memos were prepared one month after Zubaydah had already been subjected to the specific techniques authorized in an August 1, 2002, memo. John Kiriakou stated in July 2009 that Zubaydah was waterboarded in the early summer of 2002, months before the August 1, 2002, memo was written.
