At age 57, Rahm Emanuel boasts a remarkably broad set of experiences for evaluating the young administration of President Donald Trump. He served in Bill Clinton's White House and ran Barack Obama's as chief of staff.

As a member of Congress, he helped Democrats win back control of the House in 2006. As mayor of America's third-largest city, Emanuel huddled in December with the president-elect at Trump Tower in New York. Yet he's also been the target of Trump's barbs over surging gun violence and the "sanctuary" Chicago provides illegal immigrants.

Emanuel sat down to discuss the new president over a beer in a tavern near Wrigley Field. What follows is a condensed, edited transcript of their conversation.

HARWOOD: You met with Donald Trump. What was he like?

EMANUEL: That's a different moment when you become president. And it kind of comes upon you in one sudden rush and then in waves.

I think the jury is out whether this is the early stage — kind of a learning process — that goes on in any White House when you first arrive. Or this is, because of the style and the improv, just going to be constant like this. And the jury is out about which one it is.

I used to say to President Clinton, when I was his senior advisor, that if we knew in the first year of the first term what we knew by the first year of the second term we'd be geniuses. There's nothing like having been there.

HARWOOD: What is the attitude that you think Democrats should take to Donald Trump? Is it one of massive resistance or is it looking for places to cooperate?

EMANUEL: We should express ourselves. My general attitude is, cooperate where you can, but confront when you must.

HARWOOD: You said Democrats need to take a chill pill. What did you mean by that?

EMANUEL: This is a marathon, it's not a sprint. This is not going to just turn around in 2018. Don't just bet that he's going to collapse.

We have to have ideas, real answers to challenges that people are facing. You have to have the political capacity and staying power and stamina.

HARWOOD: Did Obama and people like you dig the hole the Democrats are in?

EMANUEL: There's other forces besides the Obama presidency. The technology, global economy, stagnant incomes that played a big role. But you've also got to look at, what were the political implications of policies, and were there political upsides or downsides?

HARWOOD: Let me ask you what you think is going to happen to three signature legacies of the president. Obamacare, which Republicans are struggling with repealing, replacing now. Dodd-Frank. And you already talked about the Dreamers.

EMANUEL: I don't think the president will touch Dreamers. Dodd-Frank, I think they are going try to fundamentally undermine it. I think not just in the consumer office, but the Volcker Rule, how much cash banks have to have, the kind of checkup to make sure that they're healthy.

Of the three you're talking about I think that's the one that's most vulnerable.
