Barack Obama: “As a country, we've got to do everything we can to make sure that every single young person here can have that 'aha'…”

People need to “rediscover what’s the story we tell about how we’re going to live together, and see each other, and recognise each other, and disagree, and yet, still care for each other”.

When we choose, when we make that decision, I do believe – and there is evidence for this – that the world gets incrementally better, and that is a worthy goal and it’s worth fighting for.

And I will fight for that, even if I don’t always think it’s going to win.

It is a basic principle of American democracy that the government can’t selectively target individuals simply because of their political beliefs or what they say.
