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

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.

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.

When we have an effort made at sanctions involving many other nations it has a potential of greater impact on Russia and discouraging Putin.
