The 9/11 Public Discourse Project was started by the ten members of the National Commission on Terrorist Attacks upon the United States, or 9/11 Commission, to continue efforts toward implementation of the 9/11 Commission recommendations after the Commission's congressional mandate expired on August 21, 2004. The PDP was established as a non-profit tax-exempt organization, with the ten members of the 9/11 Commission serving as its board of directors. Originally conceived as a one-year project, it was supported in its first year largely by the William and Flora Hewlett Foundation. Under the directorship of Christopher Kojm, who had served as deputy to 9/11 Commission vice-chair Lee Hamilton, the commissioners undertook extensive congressional testimony and public appearances. As it became clear that the work of implementation was going to be a great deal more complex than anticipated, they sought funding for additional time, provided by the Knight Foundation and by a grant from the Smith Richardson Foundation. Their seven public sessions on "The Unfinished Agenda" in June and July 2005 were a prelude to the intensive reports on implementation in fall 2005, culminating in December with the widely publicized "report card" sessions that graded the executive and legislative branches of government as well as relevant law enforcement agencies on their implementation of the recommendations in the 9/11 Commission's report. The project ceased operation on December 31, 2005.
