With classified material also found at former Vice President Mike Pence's home, there is now a palpable sense in the halls of power that as more officials or ex-officials scour their cabinets or closets, more such oops moments will emerge.
On Thursday, the National Archives wrote to representatives of all ex-presidents and ex-vice presidents back to the Reagan administration to ask that their personal records be checked anew for any classified documents, according to two people familiar with the matter. They were not authorized to speak about document investigations and spoke on condition of anonymity.
The Carter files fell into Kristin's hands through a somewhat meandering route.
Two days after the 1980 debate, businessman Alan Preble found the papers in his Cleveland hotel room, apparently left behind by Carter press secretary Jody Powell. Preble took them to his Franklin Park home, where they sat for more than three years as a faintly appreciated keepsake.
“We had looked through them but didn’t think they were important,” Carol Preble, Kristin's mother, said back then, apparently unimpressed by the classified markings. But for social studies class, Kristin "thought they’d be real interesting. I thought they’d be great, too."
Off the girl went to Ingomar Middle School on Jan. 19, 1984, with the zippered briefcase.
Teacher Jim DeLisio's eyes popped when he saw the warnings on the documents inside. Among them: “Classified, Confidential, Executive” and “Property of the United States Government."
“I truly didn’t want to look at it,” he said then. “I was just too … scared. I didn’t want to know.”
Curiosity got the better of him. That night, he said, he and his wife and daughter pored over the documents, containing “everything you’d want to know from A to Z” on world and U.S. developments. One folder was marked “Iran." Libya was also in the mix.
Unable to reach Kristin's family by phone, DeLisio the next day called the FBI, which swiftly retrieved the papers.
A Justice Department official who spoke to The Associated Press on the condition of anonymity at the time said the bundle of documents was 4 inches (10 centimeters) thick.
Despite steering the secrets back to their proper place, DeLisio was reprimanded by school officials for calling the authorities before reaching the Preble family or them. The discovery fed into a broader investigation by a Democratic-led congressional committee of the official Carter papers obtained by the winning Reagan campaign.
The Reagan Justice Department declined calls by the committee to appoint a special counsel in that matter. A court case trying to force that appointment failed, and no criminal case was brought. Debategate faded, but not the concern over how classified documents are handled by those in power.
As for Kristin, she earned a niche in history and a “B” on her school project.
