What is happening in Iraq now is awful, but it is a consequence of our invasion, not our withdrawal.

The anti-gun-violence movement was essentially asleep from 1994 to 2012, and during that time, the gun lobby built up enormous political power.

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

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.

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.

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.
