Let's look at the full quote since Breitbart has a habit of writing headlines that have an only tenuous relationship to the story they then go on to post in more detail.
"There’s no kid in America who can’t look at our Olympic team and see themselves somewhere. That’s part of the reason why we’re successful — because we gather talent from every corner of the globe. And through the years of people arriving — whether it’s in Ellis Island or Angel Island or coming over the Rio Grande; some cases, coming not of their own accord — we’ve become something more than just the sum of our parts. We’ve become Americans together. And there’s something special about that — all races, all faiths, all traditions, all orientations, all marching together under that same proud flag. Not bound by a creed or a color, but by our devotion to an enduring set of ideals: That we’re all created equal, that we can think and worship and love as we please, and that we can pursue our own version of happiness."
