TUCSON, Ariz. - (AP) - The nation got its first look on Monday at the22-year-old loner accused of trying to assassinate Rep. GabrielleGiffords. Jared Loughner, head shaved, a cut above the right templeand his hands cuffed, scanned a packed courtroom and sat down.
His attorney, who defended Oklahoma City bomber Timothy McVeighand "Unabomber" Ted Kaczynski, whispered to him.
The judge asked Loughner if he understood that he could get lifein prison - or the death penalty - for killing federal Judge JohnRoll, one of the six who died in the shooting rampage at Giffords'meeting with constituents on Saturday in Tucson.
"Yes," he said, standing at a lecturn in his beige prisonjumpsuit. A U.S. marshal stood guard nearby.
The judge ordered Loughner held without bail. Throngs of reporters and television news crews lined up outsidethe federal courthouse, where the hearing was moved from Tucson.The entire federal bench there recused itself because Roll was thechief judge.
Hours earlier, the nation observed a moment of silence for thevictims of the rampage, from the South Lawn of the White House andthe steps of the U.S. Capitol to legislature beyond Arizona and theInternational Space Station.
There, Giffords' brother-in-law, Scott, the commanding officer,spoke over the radio. Flight controllers in Houston fell silent.
"As I look out the window, I see a very beautiful planet thatseems very inviting and peaceful," he said. "Unfortunately, it isnot."
"These days, we are constantly reminded of the unspeakable actsof violence and damage we can inflict upon one another, not justwith our actions, but also with our irresponsible words," he said.
"We're better than this," he said. "We must do better."
On a frigid morning outside the White House, President BarackObama and first lady Michelle Obama stood side by side, each withtheir hands clasped, heads bowed and eyes closed.
On the steps of the U.S. Capitol, congressional staff and otheremployees did the same.
At the Supreme Court, the justices paused for a moment ofsilence between the two cases they were hearing Monday morning.Arizona's chief federal judge, John Roll, was killed in the attack.
The president called for the country to come together in prayeror reflection for those killed and those fighting to recover.
"In the coming days we're going to have a lot of time toreflect," he said. "Right now the main thing we're doing is tooffer our thoughts and prayers to those who've been impacted,making sure we're joining together and pulling together as acountry."
In total, 19 people were shot in the rampage outside asupermarket where Giffords held here meeting. Giffords was shot inthe head, and remains in intensive care.
Among the six people killed were a 9-year-old girl who was bornon the day of the Sept. 11, 2001 terrorist attacks and wasinterested in public service, as well as one of Giffords' aides.
Loughner was tackled to the ground minutes after the shootingbegan, authorities said. He has been silent ever since.
