Generally the Constitution is a charter of negative liberties, says what the states can't do to you, says what the federal government can't do to you. But it doesn't say what the state or federal government must do on your behalf.

I do want to once again speak directly to the Iranian people. Yours is a great civilization with a vibrant culture that has so much to contribute to the world - in commerce and in science and in arts. For decades, your government's threats and actions to destabilize your region have isolated Iran from much of the world, and now our governments are talking with one another. Following the nuclear deal, you, especially young Iranians, have the opportunity to begin building new ties with the world.

If any individual who objects to government policy can take it in their own hands to publicly disclose classified information, then we will never be able to keep our people safe or conduct foreign policy.

We forget now, but during his life, Dr. King wasn't always considered a unifying figure. Even after rising to prominence, even after winning the Nobel Peace Prize, Dr. King was vilified by many, denounced as a rabble rouser and an agitator, a communist and a radical. He was even attacked by his own people, by those who felt he was going too fast or those who felt he was going too slow; by those who felt he shouldn't meddle in issues like the Vietnam War or the rights of union workers.

If we're not vigilant foreign countries can have an impact on the political debate in the United States in ways that might not have been true 10, 20, 30 years ago in - in part because of the way news is transmitted and in part because so many people are skeptical of mainstream news organizations that - everything's true and everything's false.

I would not be running for President if I didn't believe with all my heart that this is what the vast majority of Americans want for this country. This union may never be perfect, but generation after generation has shown that it can always be perfected. And today, whenever I find myself feeling doubtful or cynical about this possibility, what gives me the most hope is the next generation - the young people whose attitudes and beliefs and openness to change have already made history in this election.

I am going to be able to present to the incoming administration a country that is stronger. A federal government that is working better and more efficiently. A national security apparatus that is both more effective and truer to our values. Energy policies that are resulting in not just less pollution, but also more jobs.
