It's the 11th anniversary of the 9/11 terrorist attacks, and almost everything that happens — or doesn't happen — in politics Tuesday will be marked in some way by that event.
President Barack Obama, first lady Michelle Obama and White House staff will gather on the White House South Lawn to observe a moment of silence. The first couple also will attend an observance ceremony at the Pentagon Memorial, plus President Obama will visit wounded warriors and their families at Walter Reed National Military Medical Center in Bethesda, Md.
Vice President Joe Biden will attend a memorial service at Shanksville, Pa., where one of the four hijacked airliners crashed.
Mitt Romney, meanwhile, will speak at the National Guard Association of the United States General Conference and Exhibition in Reno, Nev. Members of the National Guard were deployed after the 2001 attacks.
Paul Ryan plans to spend Tuesday in his home state of Wisconsin and has no public events scheduled.
And both presidential campaigns have suspended negative campaign ads for the day.
On Capitol Hill, there will be a bipartisan Congressional Remembrance Ceremony on the east front steps of the Capitol. Those attending will include House Speaker John Boehner, Senate Majority Leader Harry Reid, House Minority Leader Nancy Pelosi and Senate Minority Leader Mitch McConnell.
And then there is this: Former President Bill Clinton, who gave a stemwinder last Wednesday at the Democratic National Convention, will speak at a Tuesday evening rally in Miami for Obama. Clinton also will campaign for Obama in Orlando on Wednesday. Clinton aides say he will stump for Obama in as many other battleground states as his schedule allows.
