For this 4th of July weekend, our "50 Weeks That Shaped America" series lands in, no surprise, 1776 and the signing of the Declaration of Independence. 250 years ago, a group writing assignment fell in Thomas Jefferson's lap, and he drafted a document that spurred a revolution.Jody, Niki and Kellie travelled up to Boston to WBUR's Cityspace and were joined by A.J. Jacobs, author of "The Year of Living Constitutionally" to talk about how the document came together, some of the key changes that were made to it -- and how it has served as a guiding light in the 250 years since.Join our America250 newsletter community!
