CNN recently updated their compiled list of Fast Facts about the September 11 Commission Report. The article includes facts, commission members, commission topics and a timeline.
Below is a portion of the timeline section from the article:
July 2015- The Interagency Security Classification Appeals Panel declassifies and authorizes the release of some 9/11 Commission documents, including one on FBI files related to 9/11. The file, dubbed "Document 17" or "File 17" in media reports because it is the 17th of 29 released, contains information about links between Saudi Arabia and the 9/11 hijackers. It has much of the same information contained in the 28 pages of a congressional report on 9/11, which are released about a year later.
