Barack Obama: “His thoughts and prayers are with his wife and children.”

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”.

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

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

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.
