What scandal facilited the sale of arms to Iran and occurred while John Poindexter was Deputy national Security Advisor?
Iran–Contra affair The Iran–Contra affair (Persian: ماجراي ایران-کنترا‎ ‎ , Spanish: "caso Irán-Contra" ), also referred to as Irangate, Contragate or the Iran–Contra scandal, was a political scandal in the United States that occurred during the second term of the Reagan Administration. Senior administration officials secretly facilitated the sale of arms to Iran, which was the subject of an arms embargo. They hoped, thereby, to fund the Contras in Nicaragua while at the same time negotiating the release of several U.S. hostages. Under the Boland Amendment, further funding of the Contras by the government had been prohibited by Congress.
Impeachment process against Richard Nixon An impeachment process against Richard Nixon was formally initiated on February 6, 1974, when the United States House of Representatives passed a resolution, , giving its Judiciary Committee authority to investigate whether sufficient grounds existed to impeach Richard Nixon, the 37th President of the United States of high crimes and misdemeanors, primarily related to the Watergate scandal. This investigation was undertaken one year after the United States Senate established a select committee to investigate the 1972 break-in at the Democratic National Committee headquarters at the Watergate office complex in Washington, D.C. and the Nixon Administration's attempted cover-up of its involvement.
