"I did not know many of the details relevant to the Iran and contra initiatives"

Fawn Hall's quote is most likely referring to the Iran-Contra Affair, a political scandal that took place throughout the Reagan administration in the 1980s. The scandal included the United States federal government privately selling arms to Iran in exchange for the release of American hostages held in Lebanon. The earnings from the arms sales were then utilized to money the Contra rebels in Nicaragua, which remained in violation of a congressional restriction. Hall's quote recommends that she was not knowledgeable about the information of the scandal, which is easy to understand given the complexity of the scenario. It is most likely that Hall was not privy to the inner functions of the Reagan administration and was not familiar with the full level of the scandal. Hall's quote serves as a tip of the importance of comprehending the information of a scenario prior to making any decisions.
