(WHAS11) -- In the Presidential race, both candidates have suspended active campaigning on Monday while they remember the anniversary of Sept. 11.
The President spoke at the Pentagon. While Republican Presidential nominee Mitt Romney spent the anniversary speaking to members of the National Guard in Nevada.
The President spent the morning remembering Sept. 11. On Monday afternoon he made a private visit to Walter Reed Medical Center. He visited with injured soldiers and their families.
President Obama and the First Lady began the day with a moment of silence at the White House.
They then went to the Pentagon where the President lay a wreath and spoke to families who lost loved ones.
"On a day when others sought to bring this country down, we chose to build it up with a national day of service and remembrance," Obama said.
On the way back to the White House the President and First Lady made an unscheduled stop at Arlingon National Cemetery.
They visited the graves of service members killed in Afghanistan and Iraq. The Obamas walked in between rows of the most recent soldiers who died.
Mitt Romney also made an impromptu stop and met with Chicago firefighters and first responders on the tarmac at O'Hare Airport.
The firefighters were holding a moment of silence before Romney arrived. Romney later spoke to the National Guard Association Convention.
"And among those taking the lead were members of the National Guard," Romney said.
At the Capitol, Members of the House and Senate filled the steps to honor 9/11 victims.
"We are Americans and this is our place," Rep. John Boehner (R), Speaker of the House, said.
Vice President Joe Biden attended a service in Shanksville, Pa. where Flight 93 went down.
"What they did for this country is still etched in the minds of not only you but millions of Americans," Biden said.
The candidates will resume campaigning Tuesday. Former President Bill Clinton will be on the trail for the President starting Monday night.
