It is entirely possible that these two attackers were radicalized to commit this act of terror. And if so, it would underscore a threat we’ve been focused on for years — the danger of people succumbing to violent extremist ideologies. We know that ISIL and other terrorist groups are actively encouraging people — around the world and in our country — to commit terrible acts of violence, often times as lone wolf actors. And even as we work to prevent attacks, all of us — government, law enforcement, communities, faith leaders — need to work together to prevent people from falling victim to these hateful ideologies. More broadly, this tragedy reminds us of our obligation to do everything in our power, together, to keep our communities safe. We know that the killers in San Bernardino used military-style assault weapons — weapons of war — to kill as many people as they could. It’s another tragic reminder that here in America it’s way too easy for dangerous people to get their hands on a gun. For example, right now, people on the No-Fly list can walk into a store and buy a gun. That is insane. If you’re too dangerous to board a plane, you’re too dangerous, by definition, to buy a gun. And so I’m calling on Congress to close this loophole, now. We may not be able to prevent every tragedy, but — at a bare minimum — we shouldn’t be making it so easy for potential terrorists or criminals to get their hands on a gun that they could use against Americans.

Here's the advice I give everyone about marriage — is she someone you find interesting? … You will spend more time with this person than anyone else for the rest of your life, and there is nothing more important than always wanting to hear what she has to say about things … Does she make you laugh? And I don’t know if you want kids, but if you do, do you think she will be a good mom? Life is long. These are the things that really matter over the long term.

Freedom is not an accident. Progress is not an accident. Democracy is not an accident. These are things that have to be fought for. You’re part of that legacy. They must be won. And they’ve got to be tended to constantly and defended without fail.
