Barack Obama: “The concern is, is that until we actually stop the flow, we've got problems.”

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.

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

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