During an examination of alleged campaign finance irregularities of the 1996 presidential campaign, investigators discovered that a computer glitch had caused the White House's automated record management system (ARMS) to improperly scan, log, and archive incoming, external e-mails to almost 500 White House staff members. The problem was discovered in June 1998. As a result, these emails were not turned over in response to a congressional subpoena. (The White House did turn over more than 7,000 emails in response to subpoenas in the inquiry).
