I do believe that [climate change] is real.

There is scientific evidence that demonstrates there is some impact from human activities. However I don't think the evidence is conclusive.

If Vladimir Putin is conscious and aware of his standing in the world economy, he has to understand this aggression in Crimea is not helping the reputation of Russia as a modern nation where you can do business. He's back to the old Soviet ways and a lot of folks are going to hold back and pull back as a result of it. I think he may have second thoughts.

The best way to marginalize the Muslim Brotherhood [in Egypt] is in the ballot box, not through arrests and killing people.

Governor Romney is suffering from political amnesia.

[Putin] is a bully. And bullies only understand when we punch them in the nose, but we need to do that economically.

If we were to impose greater sanctions on economic sectors, I think we could have a significant impact on Putin.
