Friend --This week, two U.S. senators, a Democrat and a Republican with "A" ratings from the NRA, introduced a bill to close loopholes in background checks for all commercial gun sales. Let that sink in for a minute. Millions of Americans have demanded action, and Congress is listening.Now that we've got legislation, the next step is passing it. And no surprise here: Allies of the gun lobby are threatening to block a vote. You can be damn sure they're going to do the same thing if the bill makes it to the House, too.OFA is taking the gun lobby head on. We won't stand by silently while the families in Newtown, Aurora, and Tucson grieve. So many people have worked tirelessly for congressional action.We won't let Congress forget.
