Norah O'Donnell went inside the National Archives in D.C. to see America’s founding documents in 2024. The Declaration of Independence wasn't always protected this way. It was once displayed near a window, causing the ink to fade. Nearly all you can make out today is John Hancock's "John Hancock.” Now, it's kept in the dark and guarded around the clock, in bulletproof cases designed to remain sealed for 100 years.#fourthofjuly #declarationofindependence #nationalarchives #ushistory
