I think Ronald Reagan changed the trajectory of America in a way that Richard Nixon did not and in a way that Bill Clinton did not. He put us on a fundamentally different path because the country was ready for it.

I've said very clearly, including in a State of the Union address, that I'm against 'don't ask, don't tell' and that we're going to end this policy.

I want to deal with the homeless situation here in Washington, D.C. I think it is a travesty that we've got men - and increasingly women - families, across the street and the in shadow of this great capital, that shows a lack of concern, not just for the capital, but for American, when we are allowing something like that to happen.

For all the noise and anger that too often surrounds the immigration debate, America has nothing to fear from today's immigrants. They have come here for the same reason that families have always come here-for the hope that in America, they could build a better life for themselves and their families. Like the waves of immigrants that came before them and the Hispanic Americans whose families have been here for generations, the recent arrival of Latino immigrants will only enrich our country.

We are willing to uphold principles that have resulted in unprecedented prosperity and security throughout Europe and around the world. With the threat of climate change only becoming more urgent, Angela [Merkel] and I focused on the need for American and E.U. leadership to advance global cooperation.
