Our system of checks and balances requires policymakers to have accurate information about government actions.
Let me be crystal clear: There is no such thing as 'limited use' nuclear weapons, and for a Pentagon advisory board to promote their development is absolutely unacceptable.
The criteria for serving one's country should be competence, courage and willingness to serve. When we deny people the chance to serve because of their sexual orientation, we deprive them of their rights of citizenship, and we deprive our armed forces the service of willing and capable Americans.
Instead of starting a new nuclear arms race, now is the time to reclaim our Nation's position of leadership on nuclear nonproliferation efforts.
Banning guns addresses a fundamental right of all Americans to feel safe.
My mother emigrated from Russia as a young child. She couldn't speak English and had no education. Her father died at age 32, leaving the family destitute. An uncle, who worked as a carpenter, supported the family.
Global warming is real. It is happening today. It is being charted by our satellites. It is being charted by our scientists. It is being charted by those of us in this body, and I think the real key is if we are ready to admit that fact and take the action to make the necessary conversion.
We cannot expect to keep our nation's secrets secure - or provide meaningful oversight for our intelligence agencies - if proper classification of our country's secrets is as likely as a coin flip.
College costs continue to rise, and student loan debt threatens to price many Americans out of a college education and out of the middle class.
Student loan debt is certainly not a fitting topic for a commencement speech, but it's an issue we must confront - not only for thousands of college graduates who deserve a fair shot, but also for our economy.
Today we have a health insurance industry where the first and foremost goal is to maximize profits for shareholders and CEOs, not to cover patients who have fallen ill or to compensate doctors and hospitals for their services. It is an industry that is increasingly concentrated and where Americans are paying more to receive less.
For the life of me, I don't understand what honest motive there is in putting this in front of this body to philosophically debate marriage on a constitutional amendment that is not going to happen, and which is enormously divisive in all of our communities.
It is my belief that tax credits only go to people who are making money, and they generally keep it.
Designing new low-yield nuclear weapons for limited strikes dangerously lowers the threshold for their use.
The sole purpose of nuclear weapons must be to deter their use by others.
'No Child Left Behind' requires states and school districts to ensure that all students are learning and are reaching their highest potential. Special education students should not be left out of these accountability mechanisms.
Women have begun to see that if I go through that doorway, I take everybody through it.
In addition to being a terrorist recruiting tool, Guantanamo is a huge drain on taxpayer dollars.
We have no regulation of drones in the United States in their commercial use. You can see drones some day hovering over the homes of Hollywood luminaries, violating privacy. This question has to be addressed. And we need rules of operation on the border, by police, by commercial use, and also by military and intelligence use.
Let me say this: I believe closing Guantanamo is in our Nation's national security interest. Guantanamo is used not only by al-Qaida, but also by other nations, governments, and individuals - people good and bad - as a symbol of America's abuse of Muslims, and it is fanning the flames of anti-Americanism around the world.
