welcome back to "reliable sources." i'm brian stelter. one of the week's top-selling books is the 1619 projects. this, of course, started as "the new york times" magazine cover story and now blossomed into multiple books. there's both an adult version and version for kids. behind it all is "the new york times" magazine writer hannah-jones. she's joining me now to discuss both new books as well as the week's news. thank you for coming on. >> thank you for having me. >> why did you need to expand on the magazine project and present what you call here a new origin story for america? >> well, we wanted to expand for a couple of reasons. the original project was limited by both the time constraints of putting out a magazine as well as space constraint. so this gave us a chance to really expand the project, invite more historians to
