I have a range, and I'd much rather do things the nice way than the hard way, but sometimes you have to use all the tools at your disposal.

It's in our interest to continue with the Paris Agreement and to deal with climate change as the real threat it actually is.

If you want change, you have to make it. If we want progress we have to drive it.

Governing is different than campaigning, and that comes with a whole different level of responsibility.

One of the things I love about negotiations is that you have to be able to play it like an orchestra, different instruments for different circumstances. There's sweetness, and encouragement, and cajoling. There's pressure, there's drama, there's ultimatums.

People are consuming the news that is comfortable for them, not necessarily the news that is real or that they need to know.

Progress is the product of human agency. Things get better because we make them better. Things go wrong when we get too comfortable, when we fail to take risks or seize opportunities.
