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.

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.

Governor Romney is suffering from political amnesia.

As a former attorney general. I have the greatest respect for the criminal justice system. But it is not good at intelligence gathering.

In Maidan Square right now, you see thousands of Ukrainians protesting the Russian occupation of Crimea. So this is a Russian protest by Ukrainians who want their sovereignty. They want their freedom and they're protesting what Russia did in Crimea.

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