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.

You have to think not about what you mean but about what people hear.

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 are all sorts of shades of gray when you're working on economic policy and tax policy and health care policy. There's no gray on this issue, to me. This is a gun lobby that is raging out of control, that doesn't even represent its own members.

At some level, Trump is more radical than the NRA. In the wake of Orlando, he was calling on people to walk into bars fully armed as a means to prevent future tragedies.

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.
