Time capsules! America is full of them ... and for America 250, Congress is even creating a new one. For this year's Fourth of July holiday, C-SPAN's podcast "The Weekly" presents a time capsule of its own. The contents: What American presidents have said about time capsules — or even put in time capsules. Like pictures of themselves. Here's what Senate historian Don Ritchie once told C-SPAN: "I was present in 1976 when we actually opened a safe that was essentially a time capsule that had given to the government in 1876. And President Ford came to the Capitol just before the Bicentennial, and opened the safe, we had no idea what was inside, there were pictures of Rutherford B. Hayes and his wife and other items that were donated at the time of the first centennial." Which other presidents have included pictures of themselves in time capsules? And what else have they put in? Find out in C-SPAN's "The Weekly." Because if you're celebrating the Fourth of July — and gearing up for America 250 — you'll want to hear all about American history, the American presidency — and time capsules.
