I spent four and a half hours debating Donald Trump in three debates, which I think should put to rest any questions about my stamina.

I used to sit on the other end of Pennsylvania Avenue and wonder why the Senate was always going into recess, until in my first year I realized how intense the pressure was.

We're now on the precipice of having a potentially much better economy, but the last thing we need to do is to go back to the policies that failed us in the first place.

There is one lesson from the past, in particular, that we cannot afford to ignore: You cannot make progress on gender equality or broader human development, without safeguarding women's reproductive health and rights.

Donald Trump abuses his power, games the system, puts his own interests ahead of the country's.

I made a mistake. I should've had two accounts, one for personal and one for office. And I didn't, and I take responsibility for that.

We have to make our economy work for everyone - not just those at the top - protecting our country and protecting our planet.
