The United States remains the only major country on earth that doesn't guarantee health care to all of our people. And yet we are spending almost twice as much per capita. We have a massively dysfunctional health care system. And I do believe in a Medicare for all single-payer system, whether a small state like Vermont can lead the nation, which I certainly hope we will, or whether it's California or some other state.

I am neither frustrated nor planning anything other than being the best Secretary of State I could be.

I`m 100 percent impartial. I`m - my responsibility is to manage this primary nominating contest neutrally and fairly.

I still believe that if we stand together with courage in our convictions and love for America, our best days are ahead of us.

People sometimes ask me, "You're still in a primary - why are you criticizing [Donald] Trump?" It's because I don't want what he's saying to stand unanswered.

We're going to fight for every vote in every state. We're going to make a real difference in people's lives.

Where we have a different background [with Hillary Clinton] on this issue is we differ on the war in Iraq, which created barbaric organizations like ISIS.
