President H. W. Bush Went Against Congress’ Request
Caspar Weinberger is the former most senior member of Ronald Reagan’s cabinet. In 1992, he was indicted for perjury and obstruction of justice for his involvement in the Iran-Contra affair. He claimed not to know that there was any illegal selling of guns to Iran and other anti-government fighters in Nicaragua.
However, it was later discovered in his personal writings that indeed was involved in the selling of weapons. Congress then demanded that Weinberger answer for his crimes. President George H.W. Bush then went against their request and granted him an executive pardon just days before his trial.
