Barack Obama: “This is the challenge we must meet.”

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.

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

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.

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.
