Republicans are going to have to come to the conclusion that there's a political price for standing against 90 percent of their constituents to stand with the gun lobby.

Frankly, when you twin the language of assassination threats with Donald Trump's suggestion that a Hillary Clinton electoral victory would be illegitimate, it scares the hell out of me.

I wake up ready to right and I feel like I'm on the right side of history every day.

If we have a president who asked for a mandate on combating gun violence, as Hillary Clinton is requesting, that's going to be really impactful. I will certainly defer to her when it comes to the exact pace and content of legislative action, but I expect it will be at the top of her agenda. It will certainly be at the top of mine.

Donald Trump has a lot of supporters with a deep hatred of Hillary Clinton and access to incredibly powerful lethal weapons.

If [lawmakers] lose elections in part because of their votes on the background-check bill or their position on the terror gap bill, then there will be a rethinking of this issue within the Republican conference.

There's no more personal issue than gun violence; every one of these stories is a life lost, i'm hoping that over the long term, as I tell these stories, that it will help to open people's eyes.
