The Iran--Contra affair, also referred to as Irangate, Contragate or the Iran--Contra scandal, was a political scandal in the United States that came to light in November 1986. During the Reagan administration, senior administration officials secretly facilitated the sale of arms to Iran, the subject of an arms embargo. Some U.S. officials also hoped that the arms sales would secure the release of several hostages and allow U.S. intelligence agencies to fund the Nicaraguan Contras. Under the Boland Amendment, further funding of the Contras by the government had been prohibited by Congress.
The scandal began as an operation to free the seven American hostages being held in Lebanon by a group with Iranian ties connected to the Army of the Guardians of the Islamic Revolution. It was planned that Israel would ship weapons to Iran, and then the United States would resupply Israel and receive the Israeli payment. The Iranian recipients promised to do everything in their power to achieve the release of the U.S. hostages. The plan deteriorated into an arms-for-hostages scheme, in which members of the executive branch sold weapons to Iran in exchange for the release of the American hostages. Large modifications to the plan were devised by Lieutenant Colonel Oliver North of the National Security Council in late 1985, in which a portion of the proceeds from the weapon sales was diverted to fund anti-Sandinista and anti-communist rebels, or Contras, in Nicaragua
While President Ronald Reagan was a supporter of the Contra cause, the evidence is disputed as to whether he authorized the diversion of the money raised by the Iranian arms sales to the Contras.[3][4][8] Handwritten notes taken by Defense Secretary Caspar Weinberger on December 7, 1985, indicate that Reagan was aware of potential hostage transfers with Iran, as well as the sale of Hawk and TOW missiles to "moderate elements" within that country. Weinberger wrote that Reagan said "he could answer to charges of illegality but couldn't answer to the charge that 'big strong President Reagan passed up a chance to free the hostages'". After the weapon sales were revealed in November 1986, Reagan appeared on national television and stated that the weapons transfers had indeed occurred, but that the United States did not trade arms for hostages. The investigation was impeded when large volumes of documents relating to the scandal were destroyed or withheld from investigators by Reagan administration officials. On March 4, 1987, Reagan returned to the airwaves in a nationally televised address, taking full responsibility for any actions that he was unaware of, and admitting that "what began as a strategic opening to Iran deteriorated, in its implementation, into trading arms for hostages".
Several investigations ensued, including those by the U.S. Congress and the three-person, Reagan-appointed Tower Commission. Neither found any evidence that President Reagan himself knew of the extent of the multiple programs.[3][4][8] Ultimately the sale of weapons to Iran was not deemed a criminal offense but charges were brought against five individuals for their support of the Contras. Those charges, however, were later dropped because the administration refused to declassify certain documents. The indicted conspirators faced various lesser charges instead. In the end, fourteen administration officials were indicted, including then-Secretary of Defense Caspar Weinberger. Eleven convictions resulted, some of which were vacated on appeal. The rest of those indicted or convicted were all pardoned in the final days of the presidency of George H. W. Bush, who had been vice-president at the time of the affair.
