We may disagree about gay marriage, but surely we can agree that it is unconscionable to target gays and lesbians for who they are - whether it's here in the United States or, as Hillary (Clinton) mentioned, more extremely in odious laws that are being proposed most recently in Uganda.

I opposed the Defense of Marriage Act in 1996. It should be repealed and I will vote for its repeal on the Senate floor. I will also oppose any proposal to amend the U.S. Constitution to ban gays and lesbians from marrying.

I've always viewed the Paris Agreement as a starting point. If you look at all the commitments that have been made by all the countries, it's still not sufficient to deal with the very dangerous situation we face. What it has done is that it created an architecture whereby as technology improves, as we find new clean sources of energy, as we make our economies more efficient, then gradually we can turn up the dial and improve the outcomes of Paris.

We also recommit to supporting tribal self-determination, security, and prosperity for all Native Americans. While we cannot erase the scourges or broken promises of our past, we will move ahead together in writing a new, brighter chapter in our joint history.

David [Cameron] has been an outstanding friend and partner on the global stage and, based on our conversation, I'm confident that the UK is committed to an orderly transition out of the EU.

Whether we like it or not, we remain a dominant military superpower.

I'm willing to work with anyone of either party who has a good idea and the commitment to see through. And we should all expect you to hold us accountable for our progress or our failure to deliver.
