Joy Reid leads this episode of The ReidOut with a new symbol taking over America--the AR-15. Many Republicans celebrate the AR-15 despite the fact that mass murderers routinely use it for its intended purpose, which is to quickly kill people. Joy and her guests discuss how that weapon of war became so powerful politically for the right, and how Republicans are able to supress gun control measures the vast majority of Americans, including gun owners, support. Plus, we expose how the right is using the Nashville mass murder to put a target on the backs of transgender Americans. Additionally, in the battle over TikTok: Will Congress actually ban the wildly popular app? And is it any more of a danger than Elon Musk's Twitter or Mark Zuckerberg's Facebook? Joy will ask one of the members of Congress who supports the TikTok ban. All this and more in this edition of The ReidOut on MSNBC.
