John Tower
John Goodwin Tower (September 29, 1925 - April 5, 1991) was a conservative Republican United States Senator from Houston, Texas.

Tower served in the Pacific Theater during World War II on an amphibious gunboat. He returned to Texas after the war and completed his undergraduate courses at Southern Methodist University. In 1952-1953 he pursued graduate coursework at the London School of Economics and Political Science.
Tower's first attempt at entering the Senate in 1960 was also his first state-wide race. His opponent was Lyndon B. Johnson, who was running concurrently for both Senator and Vice President on the Democratic ticket with John F. Kennedy. Tower lost to Johnson, but the Kennedy and Johnson team had won the Presidency and the office of Senator became vacant. Tower won the special election that followed. Tower's election marked the first time since 1870 that Texas had elected a Republican to the Senate.
Tower retired in 1985 after 24 years in office. But his career in government did not end there. President Reagan asked Tower to chair the President's Special Review Board to study the action of the National Security Council and its staff during the Iran-Contra Affair. The Board, which became known as the Tower Commission, issued its report on February 26, 1987. The report was highly critical of the Reagan Administration and of the National Security Council's dealings with both Iran and the Nicaraguan Contras.
In 1989, Tower was President George H. W. Bush's choice to become Secretary of Defense, but the Senate did not confirm his nomination after much contentious debate and testimony.
Senator Tower was killed in a commuter plane crash in Georgia in 1991. His daughter also died in the crash.
Some conspiracy theorists hold that Tower's plane crash was a murder carried out by the CIA or right-wing elements, the motive being punishment for Tower's thorough investigation of the Iran-Contra Affair.
