It's time. Join more than 800 mayors and over a million grassroots supporters to demand that Congress step forward with a plan to end gun violence.

Our efforts cannot bring back the 20 innocent children murdered in Newtown, CT -- or the 33 people murdered with guns every day in America. But we can prevent future tragedies by passing common sense legislation that will:

1. Require a criminal background check for every gun sold in America
2. Ban assault weapons and high-capacity ammunition magazines
3. Make gun trafficking a federal crime, with real penalties for "straw purchasers"

Demand that your members of Congress support these legislative priorities.
