Barack Obama: “Our strength does not come from the words we've written on the page or the laws we've put down on the books.”

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.

It is a decision about how do we face and embrace this finite amount of time we have on the planet.

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 fact that any president, or any administration, is willing to engage in such transparent efforts to intimidate someone should outrage all Americans, regardless of how they feel about Congresswoman Omar’s political views.
