Here are statements from notable figures about the commemoration of the Sept. 11 terrorist attacks:
"This anniversary allows us to renew our faith that even the darkest night gives way to a brighter dawn. Today, we can come here to the Pentagon, and touch these names and kneel beside a building where a single stone still bears the scars of that fire. We can visit the field of honor in Pennsylvania and remember the heroes who made it sacred. We can see water cascading into the footprints of the Twin Towers, and gaze up at a new tower rising above the New York skyline.
"And even though we may never be able to fully lift the burden carried by those left behind, we know that somewhere, a son is growing up with his father's eyes, and a daughter has her mother's laugh -- living reminders that those who died are with us still.
"So as painful as this day is and always will be, it leaves us with a lesson that no single event can ever destroy who we are. No act of terrorism can ever change what we stand for. Instead, we recommit ourselves to the values that we believe in, holding firmly, without wavering, to the hope that we confess.
"That's the commitment that we reaffirm today. And that's why, when the history books are written, the true legacy of 9/11 will not be one of fear or hate or division. It will be a safer world; a stronger nation; and a people more united than ever before.

"Today we stand on this hallowed ground, a place made sacred by the heroism and sacrifice of the passengers and the crew of Flight 93. And it's as if the flowers, as I walked here, as if the flowers were giving testament to how sacred this ground is.
"My guess -- and obviously it's only a guess; no two losses are the same. But my guess is you're living this moment that Yeats only wrote about, when he wrote, pray I will and sing I must, but yet I weep. Pray I will, sing I must, but yet I weep.
"My personal prayer for all of you is that in every succeeding year, you're able to sing more than you weep. And may God truly bless you and bless the souls of those 40 incredible people who rest in this ground.
-- Vice President Joe Biden, speaking at a memorial service in Shanksville, Pa.
"Eleven years ago, evil descended upon our country, taking thousands of lives in an unspeakable attack against innocents. America will never forget those who perished. America will never stop caring for the loved ones they left behind. And America shall remain ever vigilant against those who would do us harm. Today we again extend our most profound gratitude to our brave troops who have gone into battle, some never to return, so that we may live in peace. On this most somber day, those who would attack us should know that we are united, one nation under God, in our determination to stop them and to stand tall for peace and freedom at home and across the world."
-- GOP presidential candidate Mitt Romney
"Eleven years ago today, from Capitol Hill, I could see the smoke rising from the fires burning in the Pentagon. Like all Americans, I will never forget the moment that our homeland came under attack. For me, this is a day to remember those who perished on that day of terror, including the first responders. It is also a day to pay tribute to all those who have worked quietly and tirelessly both on the home front and abroad to prevent a repetition of such terrible events. And it is a day to give honor to those in our military who have sacrificed so much, including their lives, for the same end. Their courage and heroism and willingness to answer the call of duty have kept America safe and strong and free. We are truly the home of the brave."
--GOP vice presidential candidate Paul Ryan
"Eleven years ago today, our country tragically lost nearly 3,000 people in the terrorist attacks on U.S. soil. As we remember those who lost their lives on that day, let us reflect on how our nation came together in a time of need. Americans consoled and supported each other. We encouraged one another to focus on recovery rather than adversity. I am eternally grateful to our military for what they do every day to protect our nation. It is because of their selfless service that America is the land of the free and the home of the brave. To those of you who lost loved ones on September 11, 2001, my thoughts and prayers remain with you."
-- Florida Attorney General Pam Bondi
"This September day remains forever etched on our memories and in the pages of our history books. Terrorists played out their evil against our nation, bringing death to thousands of innocent people and grave physical and emotional injury to thousands more.
"Once again, our thoughts and prayers are with those who perished in the unimaginable physical destruction in New York, Virginia, and Pennsylvania. And, we reflect on the acts of selflessness played out by strangers helping strangers, the boldness of our first responders, law enforcement, and military.
"More than a decade later, we can be relieved that Osama bin Laden no longer walks this earth, however, we must remain vigilant in the War on Terror. Al Qaeda and terrorists of all kinds continue to make it their life's mission to tear apart the fabric of freedom and democracy.
"As a nation, we must stand against such darkness and join hands to keep America safe for current and future generations. As a Member of Congress, my most important role is to support our military and make sure it has the tools it needs to fight terrorism. We cannot bring back those who have given their lives so we can be safe from harm. We can, however, move forward as a unified front against those who wish to harm our nation and her allies."
-- Congressman Ander Crenshaw, R-Fla.
"Eleven years ago today, our country's resolve was tested by those that wished to do our nation irreparable harm. This defining moment in our nation's history - September the 11th - remains forever in our hearts and minds. While we will never forget the tragedy that struck at the heart of our nation or the innocent lives of loved ones lost, we will always remember the burst of unity that rippled across our country.
As we honor and commemorate the service and sacrifice of those lost in the wake of September 11th, may their memory renew in all of us the courage and compassion found throughout our communities. The events surrounding September 11th represent the strength of our country and its people, and serve as a reminder that no matter what differences we may share, we are Americans first. May we never forget the American heroes that made the ultimate sacrifice for our freedom, may our prayers remain with our men and women in uniform and may God continue to bless our great nation."
-- Commissioner Adam Putnam, Florida Department of Agriculture and Consumer Services
"Today, our thoughts and prayers are with those who lost their lives in the attacks of September 11, 2001 and all families impacted by the tragic events of that day. We also thank our first responders and military members for dedicating their lives to the protection and safety of others. Their bravery and honor shapes the very character of our nation."
-- Fla. Gov. Rick Scott
