Bush second from left, and former first lady Laura Bush arrive at the National September 11 Memorial for a ceremony marking the 10th anniversary of the attacks at World Trade Center, Sunday, Sept. 11, 2011.
President Barack Obama has been briefed by his top national security aides on the government's preparedness ahead of the 11th anniversary of the Sept. 11 attacks.
The White House said Monday the president and his advisers discussed specific measures the administration was taking to prevent 9/11-related attacks. They also discussed steps that were being taken to protect Americans abroad and U.S. forces serving in combat zones.
The White House did not detail any of the measures being taken, noting only that Obama instructed government agencies to do everything possible to protect the American people both at home and abroad.
It will be 11 years on Tuesday since the terror attacks that killed nearly 3,000 people.
