Barack Obama: “Now is not the time to stop.”

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.

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.

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