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.

The cavalier casual way that Donald Trump talks about nuclear weapons is not only frightening but it goes counter to more than 70 years of bipartisan, presidential leadership of Republicans and Democrats who believed that we have to prevent other countries from getting nuclear weapons and we have to do what we can to decrease the number of nuclear weapons in the world.

We need to be as well prepared to defend ourselves against public health dangers as we should be to defend ourselves against any foreign danger.

[Donald Trump] suggestions that the United States should leave the Pacific and let Japan, South Korea, or whoever else wants to develop nuclear weapons. These are incredibly dangerous ideas that need to be confronted.

I have a very positive and optimistic view about what we can do together. That's why the slogan of my campaign is 'Stronger Together.' Because I think if we work together, if we overcome the divisiveness that sometimes sets Americans against one another, and instead we make some big goals - and I've set forth some big goals: Getting the economy to work for everyone, not just those at the top, making sure that we have the best education system from preschool through college, making it affordable, and so much else.

It is not enough to preach about family values, we must value families.

What I found when I became Secretary of State was a lot of doubts and a lot of concerns and fears from friends, allies, around the world.
