奥巴马演讲视频：奥巴马总统就华盛顿海军基地枪击案发表声明（在线收听）

THE PRESIDENT: Good afternoon, everybody. Please have a seat. Before I begin, let me say a few words about the tragedy that's unfolding not far away from here at the Washington Navy Yard. That's part of why our event today was delayed.

I've been briefed by my team on the situation. We still don't know all the facts, but we do know that several people have been shot, and some have been killed. So we are confronting yet another mass shooting -- and today, it happened on a military installation in our nation's capital.

It's a shooting that targeted our military and civilian personnel. These are men and women who were going to work, doing their job, protecting all of us. They're patriots, and they know the dangers of serving abroad -- but today, they faced unimaginable violence that they wouldn't have expected here at home.

So we offer our gratitude to the Navy and local law enforcement, federal authorities, and the doctors who've responded with skill and bravery. I've made it clear to my team that I want the investigation to be seamless, so that federal and local authorities are working together. And as this investigation moves forward, we will do everything in our power to make sure whoever carried out this cowardly act is held responsible.

In the meantime, we send our thoughts and prayers to all at the Navy Yard who've been touched by this tragedy. We thank them for their service. We stand with the families of those who've been harmed. They're going to need our love and support. And as we learn more about the courageous Americans who died today -- their lives, their families, their patriotism -- we will honor their service to the nation they helped to make great. And obviously, we're going to be investigating thoroughly what happened, as we do so many of these shootings, sadly, that have happened, and do everything that we can to try to prevent them.
