Barack Obama: “The scale of our challenges may be great.”

I think when we act on that basis, it doesn't always work out, but over time things do get better.

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.

If I had a blame pie for why politics is so polarised and why we're seeing a rise of populism in many places, it's because of that information that is going into our brains every day.

I’m going to insist that we can do better than we’re doing right now.
