Barack Obama: “The Ukrainian government has acted responsibly and seriously, and we commend them for that.”

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.

The full weight of the federal government is being brought down on a law-abiding elected official because she has dared to criticize the president.

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.
