BREWER: I am just heartbroken. Gabby is more than just a colleague; she's actually a friend. She's always been a noble public servant, and my thoughts and my prayers are with Congresswoman Giffords and her family, the congresswoman's staff and their families, as well as other victims of this senseless and cruel violence. It's an unbelievable tragedy that the people of Arizona experienced today.
AMANPOUR: Last night, this was the scene outside the hospital in Tucson, as supporters and friends of the congresswoman and the other victims gathered and stood vigil, waiting for news.
AMANPOUR: And the sheriff has just come out within the last 15 minutes or so saying that, in fact, in total, there were 20 victims dead and wounded, 20, not 19, so that's the latest figure that we have.
I'm joined now by George Stephanopoulos, anchor of "Good Morning America," and obviously longtime friend of "This Week."
There's no motive yet. The perpetrator is silent so far. No connections yet to what happened. What does this mean for the -- really, for the story of this nation?
STEPHANOPOULOS: Well, we should say there's so much we don't know yet about the killer, about -- you know, we know he was unhinged in some way. We don't know whether he was politically motivated in an active way.
But we do know this. This is a moment for the country. You saw the sheriff there talk about a time for a little soul-searching, and that has already begun, I think, in this country, questions about, has the political debate gotten too hot? Has all this anger boiling over in the country in some way reached out and touched people in a way that might in some way motivate violence?
It's going to lead to big questions, Christiane, for Congress. How will their security change in the wake of all this?
AMANPOUR: Do you think that debate can actually be had? Because already you're seeing that debate itself being polarized.
STEPHANOPOULOS: Well, and that's the world we live in right now. And, again, to stress, we don't know if this is more like Columbine and Virginia Tech -- just a crazy person, unhinged -- or Oklahoma City, where the bomber was much more politically motivated, he was very conscious of his political motivations.
But this is something that people were already worried about. This is not the first time that we've seen attacks against government officials, even though it's the first attack against a member of Congress in 30 years, already this week, those two package bombs to the government offices in Maryland and Washington, D.C.
AMANPOUR: And we're going to be delving into this all throughout this hour, and you're going to stay with us, George, so thank you so much.
And right now, we're joined by a close friend of the congresswoman's family, Tillman Fertitta from Houston.
Mr. Fertitta, thank you so much for joining us. You have just spoken to the family overnight. Can you tell us the latest on Congresswoman Giffords' condition, please?
FERTITTA: I mean, she's in critical condition, and it's going to be very tough for the next few days and then even after that. And I think that the family's prepared for it, and they know that Gabby's one of the toughest fighters there is out there, and everybody's praying for her.
