Tower Commission

The Tower Commission was created on 26 November 1986 by U.S. President Ronald Reagan in response to the Iran Contra scandal. Reagan appointed Republican and former Senator John Tower of Texas, former Secretary of State Edmund Muskie, and former National Security Advisor Brent Scowcroft.
The Commission's report, published on 26 February 1987, concluded that CIA Director William Casey, who supported the Iran-Contra arrangement, should have taken over the operation and made the President aware of the risks and notified Congress as legally required. 
The Commission's work was continued by the Congressional Committees Investigating The Iran-Contra Affair, which were formed in January 1987 and published a report in November 1987; and by Independent Counsel Lawrence Walsh, appointed 1 December 1986 and publishing a final report in 1993.
