Vice President Joe Biden is pushing aside the scandals plaguing his boss to renew his war on guns, an unusual doubling down on a key fight the administration was humiliated on just two months ago.

In an email to supporters, Biden said, "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."

Biden was the architect of the administration's gun control plan that included a ban on assault weapons. But the time it made it to the Senate floor, it had been watered down to just an expanded background check program and even that lost, leaving the White House with nothing.

The president said, however, that he would try again and Biden on Friday indicated that he is itching for a new fight, though he provided no new details. Here is his email:

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.

I have nothing but complete faith that Congress will pass meaningful gun laws that will save lives -- if we do everything we can to make it happen. When we band together to create change, we can win. And make no mistake, P, it's up to us to win this fight.

Let Republicans in Congress know that you're not done fighting for common-sense reforms to reduce gun violence -- and that we won't stop until it's signed into law:

Let's do this,

Joe
