On September 12, 1994, the Department announced a two-phased inquiry into the aircraft crash that day at the White House. The Secretary asked Mr. Ronald K.

As part of this review, the Department was to examine and evaluate:


The Department further announced the Secretary's selection of an independent advisory committee to monitor and provide guidance to the review team and to ensure a comprehensive and impartial review. The advisory committee members were selected because of their national prominence, integrity and law enforcement or other relevant expertise. The advisory committee was responsible for reviewing the review team's findings and providing an independent assessment of the information contained in the final report.

Role of the Office of Inspector General

The Under Secretary for Enforcement requested the Office of Inspector General (OIG) to monitor the review and its findings and report to the Secretary on the thoroughness and objectivity of the review's final report. Also, the OIG was to comment on whether relevant information obtained during the investigation was properly consolidated and included in the final report.

The OIG's oversight role expanded to 'include subsequent events added to the scope of the review. For example, the OIG monitored the review team's examination of the October 29, 1994 shooting which occurred at the White House.

The experts' recommendations have adequately been considered and the results of their reports have been incorporated in the final report.
