This week we're bringing you our live show from Boston, which we taped at WBUR's City Space.

We had a great time meeting so many of you and now we're excited to let everyone else hear this

conversation. I'm Michelle Goldberg. I'm Ross Douthit. I'm David Leonhart. And this is the argument.

This week we're talking climate change with a special surprise guest, your senator Ed Markey.

He helped write the two highest profile climate proposals of the last decade.

Then, do election results from around the world mean that liberalism is dying?

And finally, a recommendation.

For our first segment, and we have a special guest, Ed Markey. He has been in Congress since the

bicentennial in 1976, which means he's been serving in Congress for this nation's entire third

century so far. And he has been a senator since 2013. We have a lot to ask him about President

Trump, impeachment, climate change, as I mentioned, and the upcoming 2020 campaign. Please welcome

Senator Markey. Thank you for joining us, senator. Thank you. Thanks for having me.

Obviously, one thing that's on many people's minds is President Trump and the question of what

Congress is going to do about it. And so we want to start there with Michelle.

So far, if I'm not mistaken, you've kind of taken the Nancy Pelosi line. And I guess the one I want

to ask is how Democrats can justify at this point. Now that Mueller has stood up and basically

implored Congress to do its job and kind of made clear that this wasn't an exculpatory report,

that there was evidence of obstruction of justice, that he couldn't indict, but that there is a

process in the Constitution to hold a president to account. How do Democrats justify not beginning

an impeachment inquiry? So Mueller said if we had confidence that the president clearly did not

commit a crime, we would have said so. What he's saying is that after compiling that 400 page report

in eye-watering detail, that they were unable to say that the president did not commit a crime.
