Barack Obama: “We are on track to prepare 100,000 STEM teachers by 2021.”

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

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”.

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.
