The scandal was compounded when Oliver North destroyed or hid pertinent documents between 21 November and 25 November 1986. During North's trial in 1989, his secretary, Fawn Hall, testified extensively about helping North alter and shred official United States National Security Council (NSC) documents from the White House. According to "The New York Times", enough documents were put into a government shredder to jam it. Hall also testified that she smuggled classified documents out of the Old Executive Office Building by concealing them in her boots and dress. North's explanation for destroying some documents was to protect the lives of individuals involved in Iran and Contra operations. It was not until 1993, years after the trial, that North's notebooks were made public, and only after the National Security Archive and Public Citizen sued the Office of the Independent Counsel under the Freedom of Information Act.
