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

I’m going to insist that we can do better than we’re doing right now.

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.

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