I think Donald Trump believes in putting a wall around America and hoping everything turns out OK.

It's a wonderful story for the gun lobby to tell that if you just load up schools with weapons, you'll be safer. All of the evidence suggests that homes and communities that have more weapons have more gun crimes, not less.

Ultimately, stability in Syria will come from decisions made on the ground by the Syrian people and by their immediate neighbors.

I think when you have so many people working for American-based think tanks and American-based defense companies, there is always going to be a bent towards proposing American-led solutions for foreign problems. People get paid big money in Washington to come up with ways that America can fix problems overseas, and they are not always right.

In Syria, a progressive foreign policy would have shown military restraint while pumping up our ability to gain political leverage over Syria's benefactors and providing humanitarian funding to make sure that anybody that wanted to leave Syria could.

I do not understand how people can look at the rapid spread of extremism all across the globe and not understand that it is - that it isn't coincidental to the concurrent rapid spread of a very conservative strain of Islam that is paid for out of Saudi Arabia.

More Democrats should be speaking without vetting their statements through their staff because it will feel realer.

The tweets that I send out are not written by somebody else. They're not vetted through my communications staff.

You can only explain America's gun violence problem through guns, because mental illness doesn't automatically lead to violence, and it doesn't lead to violence anywhere else but America.

People should remember that in the 2000s, the gun lobby got a lot passed: they got riders added to appropriations bills. They got immunity for the gun industry. They successfully managed the expiration of the assault weapons ban.

I would respectfully disagree that the right to own a military-style weapon is a God-given right. I didn't see that anywhere in the Bible that I read.

Background checks applied universally and nationally would take millions of illegal guns off the streets of our cities.

I grew up in a pretty economically safe, physically safe household, and, you know, now my life is defined by other people's trauma and by other people's emotional experience with it, and I think I'm richer for that, frankly.

I used to play lots of sports. I used to be a good tennis player. I used to be a decent golfer.

I play in the congressional baseball game.

If you were a Democrat getting ready to run for office in the 2000s, as I was, you were told to stay clear of guns... I really regret that. I regret having listened to that advice.

I can't throw a nickel from the Capitol without hitting a think tank that's been financed by one of the Gulf States.

Yemen is a symbol of our continued military hubris in the Middle East - an addiction Obama was supposed to cure but didn't.

I ran in 2006 as an opponent of the Iraq War, and I came to Congress to change overreliance on U.S. military power.

I'm generally pretty responsible and diligent, but people make mistakes.

Washington is agonizingly slow at learning from its mistakes. Especially in the Middle East.

The NRA has become financially dependent on more and more guns being sold - especially the expensive ones. In turn, the NRA has stated that its top legislative priority is to protect gun makers by advocating for legislation that benefits them.

Most elected officials don't want you to know about the world of political fundraising because they fear that it paints an unflattering portrait of public life.

With every new class of representatives that comes to Congress, there is a greater recognition of the perils of private financing of campaigns. I believe that by pulling back the curtain on the daily pressures faced by members of Congress, we can show the public how critical this reform is to the salvation of our democracy.
