I was the first Republican in the country to support the president's Clean Power Plan.

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.

We need to deter Putin from further actions because this is a very real threat.

You can see the actions that the Russians are trying to take in eastern Ukraine. And so it's so important that we take actions to deter further Russian aggression against the Ukrainian people.

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

I do believe that [climate change] is real.
