John Kerry: “Both sides are preparing for what may be the final showdown.”

We will communicate to the office that you're asking and that it's important to try to get to it as soon as possible.

Nothing is agreed to until everything is agreed to.

We are not, I have not, President Biden has not, we are not saying to people, you should not fly.

The message is, let's find a way to be able to make sure when we fly, we're not leaving emissions that we cannot capture.
