JUDY WOODRUFF:

There's been no shortage of attention paid to who might win the presidential election this November, but what promises can they deliver once in office?

Tonight, we examine what the early days of a Trump presidency might look like, and whether the next Congress would be an ally or a thorn in his side.

For that, we turn to Evan Osnos, a staff writer for "The New Yorker" magazine, and Seung Min Kim. She's a congressional reporter for Politico.

And welcome to both of you.

Evan, I'm going to start with you. You did write a sort a story for the latest "New Yorker" about what Trump would do in his early days in office. Let's go down the list. You start with suggesting he would renounce this global agreement on climate change. How would that work? What could he do?
