The House Sit-In: Will 90 Percent Of Us Be Heard?!

Gun control. The House sit-in. The Senate filibuster. The NRA, GOP, mass shootings. What's it all about? I wanted to find out some more information about the AR-15 since it seems to be the weapon of mass shooters. And if people have guns, can we ensure they're trained to use them? And what do gun ranges think of all this? SO. MANY. QUESTIONS. So hopefully some of them got answered for you.
