Iran–Contra affair
On November 25, 1986, President Reagan announced the creation of a Special Review Board to look into the matter; the following day, he appointed former Senator John Tower, former Secretary of State Edmund Muskie, and former National Security Adviser Brent Scowcroft to serve as members. This commission was called the Tower Commission. Towards the end, the committee said that there was no evidence to say that Reagan had anything to do with the affair.
