It was also disclosed that some of the money from the arms deal with Iran had been covertly and illegally funneled into a fund to aid the right-wing Contras counter-revolutionary groups seeking to overthrow the socialist Sandinista government of Nicaragua.
The investigations were effectively halted when Reagan's vice-president and successor, George H. W. Bush pardoned Secretary of Defense Caspar Weinberger before his trial began.
