Barack Obama: “Tonight we've learned that the president tomorrow is going to reinstitute the highly controversial Bush military…”

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.

If I had a blame pie for why politics is so polarised and why we're seeing a rise of populism in many places, it's because of that information that is going into our brains every day.

Because if this becomes the new normal, there’s no reason to believe it will stop with her — or that future presidents, in either party, won’t do the same.

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