Despite the PRA, neither the Reagan nor the George H.W. Bush administration maintained email records, even as the number of White House emails began growing exponentially. (The Bush administration would produce around 200 million.) In 1989, a federal lawsuit to force the White House to comply with the PRA was filed by several groups, including the National Security Archive, which at the time was mostly interested in unearthing the secret history of the Cold War. The suit sparked a last-minute court order, issued in the waning hours of the first Bush presidency, that prevented 6,000 White House email backup tapes from being erased.
