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

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.

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

I do believe that [climate change] is real.

We need to send a message to Vladimir Putin through stronger sanctions. We need him to understand that the sanctions that we put in place can have a significant impact on his economy that we need to deter further action from him. And understand who he is, former KGB colonel, he's a bully, and bullies only understand when we punch them in the nose but we need to do that economically. That is our strongest move at this point.

If I am going to pick and choose the laws I defend, I wouldn't be doing my duty as attorney general.

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