America must always lead on the world stage.

I think there is nothing wrong with instituting policies that say that harassment of any form, whether it comes through the Internet or whether it happens to you face to face, is unacceptable; that we've got zero tolerance when it comes to sexual harassment, we have zero tolerance when it comes to harassing people because of their sexual orientation, because of their race, because of their ethnicity.

All across the world, ...increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real.

What we shouldn't be doing is trying to take away your rights to bargain for better wages or working conditions...

Yes, this is hard. But there should be no question that the United States of America is stepping up to the plate. We recognize our role in creating this problem; we embrace our responsibility to combat it. We will do our part, and we will help developing nations do theirs. But we can only succeed in combating climate change if we are joined in this effort by every nation - developed and developing alike. Nobody gets a pass.
