In 1992, then-President George H.W. Bush pardoned Caspar Weinberger and five other individuals who had been indicted or convicted in connection with the Iran-Contra arms deal. The special prosecutor, Lawrence Walsh, was furious, accusing Bush of stifling his ongoing investigation and suggesting that he may have done it to prevent Weinberger or the others from pointing the finger of blame at Bush himself. The New York Times also reported that the investigation might have pointed to Bush himself.

This is what Walsh said: “The Iran-contra cover-up, which has continued for more than six years, has now been completed with the pardon of Caspar Weinberger. We will make a full report on our findings to Congress and the public describing the details and extent of this cover-up.”
