ABC NEWS, THIS WEEK WITH GEORGE STEPHANOPOULOS INTERVIEW WITH CHIEF OF STAFF OF THE ARMY GENERAL GEORGE CASEY, RNC CHAIRMAN MICHAEL STEELE AND DNC CHAIRMAN TIM KAINE.
GEORGE STEPHANOPOULOS, HOST: At 11:15 last night, the gavel came down. With only two votes to spare, the House had passed reform of health care. President Obama summed it up in three words: "This is history." At least one Republican called it a wrecking ball to the economy. We'll take on that debate in just a moment with the party chairs and our powerhouse "Roundtable."
But we begin with the latest on last Friday's mass killing at Fort Hood. Flags at the White House and all government buildings remain at half staff today. The Obamas will attend a memorial service at Fort Hood on Tuesday. And we are joined here in the studio this morning by the Army's chief officer, General George Casey.
Welcome to THIS WEEK.
GEN. GEORGE CASEY, ARMY CHIEF OF STAFF: Thank you, George.
STEPHANOPOULOS: And let me begin by offering our condolences to you and all of the families at Fort Hood. I know you just returned...
CASEY: Thank you very much.
STEPHANOPOULOS: ... from there. And you were able to spend some time with the wounded. What were you able to learn about what they saw and what they did when the shooting broke out?
CASEY: I'll tell you that my trip there on Friday with secretary of the army, John McHugh, was at once gut-wrenching and uplifting. And in talking to the wounded soldiers and in talking to the medical providers and soldiers who are at the site, I came away with what a horrific experience it was for them.
But also I was uplifted by the -- by what they did for each other. And when you talk to the wounded soldiers, the one thing that they all stress was how -- was their reaction, and their reaction in support of each other.
STEPHANOPOULOS: It was immediate.
CASEY: It was immediate. And just stories like medics who were next -- in another building next door at a graduation, their graduation, running from the building toward the crime scene in their caps and gowns, ripping them off as they went so they could get there to support their fellow soldiers.
STEPHANOPOULOS: Let's also get to the latest on the investigation. It's my understanding that Army investigators have concluded that Major Hasan was the only gunman?
CASEY: That is where they are now. But I don't -- I mean, I don't -- I think as the investigation continues, other things could evolve. But I think that is where they are today.
STEPHANOPOULOS: So you believe it was the only gunman right -- at least for right now, not conclusive, are you confident that he acted alone, that there were no other co-conspirators?
CASEY: George, I can't comment on the ongoing investigation. And those facts will come out over time here. We need to let the investigation take its course. And as I said, that will evolve over the coming days and weeks here.
STEPHANOPOULOS: But do you have any better understanding of why the first reports suggested there were two or three attackers?
CASEY: My understanding from being down there and talking to the investigators and General Cone was there were two or three soldiers that were seen running from the area, and people assumed that they were running from the police. And they just checked them out and have since decided that they weren't part of this.
STEPHANOPOULOS: And that's why they were released.
