the President is lecturing the rest of the world on the importance of credibility and transparency, he is going out of his way to write the U.S. Senate and the American people out of a final agreement.

In my view, this is troubling. When the President or the State Department makes a commitment on behalf of the United States, this is not something that should be taken lightly.

Why would the President come out with INDC that doesn't work mathematically?

the slightest level of scrutiny reveals a significant lack of authenticity, substance and merit.

It is a shame that the Obama administration has not made this type of effort when it comes to climate change.

I don't see how that is different.

If they are able to do something without ratification, without Congress's input, wouldn't the next Administration be in the same position to undo anything that was done?

I believe without exception they dealt with diplomatic relations, things we would do out in the world.

If the President signs a unilateral political agreement, let's say he figured a way to do that in Paris.

The reason was because this isn't where the problem is. It is in China and India and other places.

I have stood on the floor. I was down there during the time that right after Tom Steyer put in his $75 million to elect people that wanted to revive the old global warming argument.

the next President could revoke an executive agreement with Iran 'with the stroke of a pen,' and future Congresses could modify the terms of the agreement at any time.

I said no, what they are telling you isn't true. We are not going to be passing cap and trade as they told you.

I do think that Citizens United has had a really, really unfortunate effect on this conversation.

There is going to be a big accountability moment in November 2016, when the Republican party has to take what is presently its theory about carbon change.

That is not exactly true, because that was on a majority, a vote on a motion to proceed.

By the admission of President Obama's first director, Lisa Jackson, of the EPA, when asked the question when she was sitting at the table right where you are sitting today, if we were to pass some type of a cap and trade legislation…

Should this moratorium on authorizations continue, the agency will have up to 23 systems that have not been subject to a thorough security controls assessment.
