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.”
