Tower Commission
The Tower Commission was commissioned on 1 December 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 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.
