Two hundred and fifty years ago, a group of Americans signed their names to a piece of parchment and made a promise no nation had ever made before: that we're all created equal, endowed by our Creator with unalienable rights — life, liberty, and the pursuit of happiness. We're the only nation in history built not on ethnicity, or blood, or geography but on an idea. That's always been what makes us exceptional. We chose that path 250 years ago but that’s where the work began, not where it ended. Every generation has had to choose it again. At Valley Forge, at Gettysburg, on the beaches of Normandy, in the streets of Selma. Americans recommitted themselves to the principles on which our nation was founded. Now it's our turn. There's nothing guaranteed about our democracy. We have to fight for it, defend it, and earn it. Over and over, year after year. That's not a burden. That's what it means to be an American. 250 years in, we still haven't fully lived up to those words in the Declaration. But we've never walked away from them, and this July 4, I hope all of us can commit to one thing: that we never will. I don't believe we're as divided as we're told we are. I've bet my whole life on the American people, and I'm not stopping now. Happy 250th birthday, America. Our story isn't finished. Let's keep writing it together.
