“Our diversity is our superpower.”

2016, Los Angeles 2024 Summer Olympics bid
Context: Please don’t doubt us. America’s diversity is our greatest strength. Diversity is not easy. Diversity is a leap of faith that embraces all faiths. And that’s why I believe L. A. is a perfect choice for the 2024 Games, because the face of our city reflects the face of the Olympic Movement itself.

2010s, Farewell Speech (2017)
Context: If your family doesn't have much money, I want you to remember that in this country, plenty of folks, including me and my husband — we started out with very little. But with a lot of hard work and a good education, anything is possible — even becoming President. That's what the American Dream is all about.
If you are a person of faith, know that religious diversity is a great American tradition, too. In fact, that's why people first came to this country — to worship freely. And whether you are Muslim, Christian, Jewish, Hindu, Sikh — these religions are teaching our young people about justice, and compassion, and honesty. So I want our young people to continue to learn and practice those values with pride. You see, our glorious diversity — our diversities of faiths and colors and creeds — that is not a threat to who we are, it makes us who we are.

2010s, 2015, Speech on extremism (20 July 2015)
Context: It is here in Britain where different people, from different backgrounds, who follow different religions and different customs don’t just rub alongside each other but are relatives and friends; husbands, wives, cousins, neighbours and colleagues. It is here in Britain where in one or two generations people can come with nothing and rise as high as their talent allows. It is here in Britain where success is achieved not in spite of our diversity, but because of our diversity.
