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.

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

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

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

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.

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