1986- CIA Director William Casey Unable To Testify In Iran-Contra

CIA Director William Casey was suspected, by some, of involvement with the controversial Iran-Contra affair, in which the CIA secretly traded arms to the Islamic Republic of Iran, and secretly diverted some of the resulting income to aid the rebel Contras in Nicaragua, in violation of U.S. law. Casey was called to testify before Congress about his knowledge of the affair. On 15 December, 1986, one day before Casey was scheduled to testify before Congress, Casey suffered two seizures and was hospitalized. Three days later, Casey underwent surgery for a previously undiagnosed brain tumor. Casey died in hospital less than 24 hours after former colleague Richard Secord testified that Casey supported the illegal aiding of the Contras.
