In a letter to supporters Friday, Vice President Joe Biden asked supporters to help bring back support for gun control.

Friend —

Soon after our first attempt at reducing gun violence was blocked by a minority of senators, I brought together advocates for this legislation and gave them a very clear message:

This fight is far from over.

If you’re with me in the fight for common-sense legislation to reduce gun violence, let the Republicans in Congress know you’re not backing down. Add your name right now.

Look, I’ve been in politics a long time now. And I’ve seen time and time again that real, lasting change isn’t always immediate — but as long as you don’t give up, you can win battles that you never thought possible.
