In a signing ceremony at the White House, the president said one of his administration's highest priorities is to prevent the spread of nuclear weapons, and the United States and its allies have "strengthened the global non-proliferation regime, including the cornerstone of our efforts -- the Nuclear Non-Proliferation Treaty." He said Iran is the only signatory to the treaty "that has been unable to convince the International Atomic Energy Agency that its nuclear program is for peaceful purposes."
Following the session, Obama told reporters the pair discussed "issues related to Afghanistan and Pakistan; Iran and its attempts to develop nuclear weapons capacity."
"We discussed the Middle East peace process and the importance of moving forward in a significant and bold way in securing a Palestinian homeland that can live side by side with a secure and prosperous Israeli state," the president said.
During their talks, both leaders expressed strong support for getting Iran to "meet its international obligations" regarding its nuclear program and hope the proximity talks will lead to a resolution of the Middle East conflict.
Obama thanked Abdullah for his hospitality when Obama visited Riyadh and pointed out the historic ties between the United States and Saudi Arabia dating back to the meeting 70 years ago between Franklin Delano Roosevelt and King Aziz.
Abdullah echoed the sentiments and said he has heard from people around the world who consider the American people "friends of Saudi Arabia and its people and … friends of the Arab and Muslim people, and … also friends of humanity."
"One hundred members of the Senate sit here in the shoes of more than 300 million Americans as we discharge our duties," committee Chairman Patrick Leahy said. "The Supreme Court stands for all Americans ... it is an awesome responsibility."
If confirmed, President Barack Obama's second Supreme Court nominee -- now the solicitor general -- would be the fourth female justice and third woman sitting on the court, joining Ruth Bader Ginsburg and Sonia Sotomayor.
Police Constable Rob McDonald said several dozen people were taken into custody at a University of Toronto building for allegedly wielding "street-type weaponry" that included bricks, bats, sharpened sticks and bottles of fluid -- "items you don't need for a weekend in Toronto," The Globe and Mail reported. No guns or knives were found, he said.
Canadian TV network CTV reported police fired rubber pellets and blank rifle shots to push back about 100 demonstrators during what apparently had been a peaceful sit-in outside a detention center.
The network said the group was chanting "peaceful protest, peaceful protest" when police moved into the crowd to grab a known anarchist. That triggered a reaction from the group, prompting the police response and more arrests.
On Saturday, an apparent breakaway group of about 70 protesters set fire to police cars, hurled bricks, and smashed store and office windows, the Toronto Star reported.
The protests, which drew thousands of demonstrators to the economic summit, halted downtown subway service much of Saturday and forced the closing of some hospitals and businesses as police corralled demonstrators by the busloads.
Officers, some pelted with bricks or other projectiles, fired tear gas for the first time in Toronto's history at Queen and Peter streets, Toronto Police Chief Bill Blair said. "We have never seen that level of wanton criminality and destruction on our streets," Blair said.
Some protest organizers told the newspaper police had intimidated and arrested peaceful demonstrators.
The Guardian confirmed Jesse Rosenfeld, a Canadian journalist freelancing for the British newspaper, was arrested during the protests Saturday night.
Steve Paikin, host of public station TVOntario's "The Agenda," witnessed the arrest and tweeted that he saw Rosenfeld, 26, being held by two officers while another punched him and drove an elbow into the man's back. Paikin called it "totally unnecessary" use of force and "police brutality."
