2013, "Let Freedom Ring" Ceremony (August 2013)
Context: p>Everyone who realizes what those glorious patriots knew on that day -- that change does not come from Washington, but to Washington; that change has always been built on our willingness, We The People, to take on the mantle of citizenship -- you are marching.And that’s the lesson of our past. That's the promise of tomorrow -- that in the face of impossible odds, people who love their country can change it. That when millions of Americans of every race and every region, every faith and every station, can join together in a spirit of brotherhood, then those mountains will be made low, and those rough places will be made plain, and those crooked places, they straighten out towards grace, and we will vindicate the faith of those who sacrificed so much and live up to the true meaning of our creed, as one nation, under God, indivisible, with liberty and justice for all.</p

2000s, 2003, Hope and Conscience Will Not Be Silenced (July 2003)
Context: By a plan known only to Providence, the stolen sons and daughters of Africa helped to awaken the conscience of America. The very people traded into slavery helped to set America free. My Nation's journey toward justice has not been easy, and it is not over. The racial bigotry fed by slavery did not end with slavery or with segregation. And many of the issues that still trouble America have roots in the bitter experience of other times. But however long the journey, our destination is set: liberty and justice for all.

2010s, 2018, Farewell statement (2018)
Context: I have tried to serve our country honorably. I have made mistakes, but I hope my love for America will be weighed favorably against them.
I have often observed that I am the luckiest person on Earth. I feel that way even now as I prepare for the end of my life. I have loved my life, all of it. I have had experiences, adventures and friendships enough for ten satisfying lives, and I am so thankful. Like most people, I have regrets. But I would not trade a day of my life, in good or bad times, for the best day of anyone else’s.
I owe that satisfaction to the love of my family. No man ever had a more loving wife or children he was prouder of than I am of mine. And I owe it to America. To be connected to America’s causes — liberty, equal justice, respect for the dignity of all people — brings happiness more sublime than life’s fleeting pleasures. Our identities and sense of worth are not circumscribed but enlarged by serving good causes bigger than ourselves.
"Fellow Americans" — that association has meant more to me than any other. I lived and died a proud American. We are citizens of the world’s greatest republic, a nation of ideals, not blood and soil. We are blessed and are a blessing to humanity when we uphold and advance those ideals at home and in the world. We have helped liberate more people from tyranny and poverty than ever before in history. We have acquired great wealth and power in the process.
