The worst part of what we heard Donald [trump] say has been about nuclear weapons. He has said repeatedly that he didn't care if other nations got nuclear weapons, Japan, South Korea, even Saudi Arabia. It has been the policy of the United States, Democrats and Republicans, to do everything we could to reduce the proliferation of nuclear weapons.

Never waste a good crisis...Don't waste it when it can have a very positive impact on climate change and energy security.

I will take a backseat to no one in keeping America safe. I have a very clear set of proposals about how we defeat ISIS.

Sometimes, opening up your eyes and realising what you have - no matter how little you think - helps you find yourself.

It was outrageous that [Donald Trump] would be advocating [that] women who exercise their constitutional right and have autonomy over their healthcare decisions would be criminals, along with the doctors that served them. He did try to walk it back - I think pretty unconvincingly.

I am not going to make promises I can't keep. I am not going to talk about big ideas like single-payer and then not level with people about how much it will cost.

I intend to be a leader of America that people can count on, both here at home and around the world, to make decisions that will further peace and prosperity, but also stand up to bullies, whether they're abroad or at home.
