Barack Obama: “I know that Brian McKeon will be an exceptional advisor and leader going forward.”

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.

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.

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.

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