Over the past few months we've heard a lot about fake news and especially its impact on the presidential election. Writers can make up stories and publish them on the web, where they're often shared on social media, making it difficult to tell fact from fiction.

Facebook wants to make it a bit easier to discern the difference. The company is partnering with several well-known fact-checking organizations to help identify and label fake news stories shared on Facebook.

One of those partners is Philadelphia-based FactCheck.org.  Its director, Eugene Kiely, explained how the new initiative will work to NewsWorks Tonight's Brad Linder.
