Barack Obama: “Russia is responsible for the violence in eastern Ukraine.”

When we choose, when we make that decision, I do believe – and there is evidence for this – that the world gets incrementally better, and that is a worthy goal and it’s worth fighting for.

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.

Looking forward to being in Detroit on 10/24 to campaign for Jocelyn Benson, Abdul El-Sayed and Democrats up and down the ballot in Michigan.

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