I've got certain responsibilities that I have to carry out in a very specific institution and in a specific moment in time.

Corporations aren’t people. People are people.

Obviously [my daughters] - and Michelle - have made a lot of sacrifices on behalf of my cockamamie ideas, the running for office and things.

My relationship with Silicon Valley and the tech community historically has been really good. Many of these folks are my friends.

More broadly, Prime Minister Lee [Hsien Loong] and I will work to advance the US-Singapore partnership across the board. We're committed to sustaining the dynamism of our economies with the Trans-Pacific Partnership - the highest-standard trade agreement ever - which will support trade and innovation in both our countries.

The most powerful political moments for me come when I feel like my actions are aligned with a certain truth. I can feel it. When I'm talking to a group and I'm saying something truthful, I can feel a power that comes out of those statements that is different than when I'm just being glib or clever.

I have seen, the desperation and disorder of the powerless: how it twists the lives of children on the streets of Jakarta or Nairobi in much the same way as it does the lives of children on Chicago 's South Side.
