Hey there, real quick before we start the show.

Since impeachment got underway, the squad here at NPR Politics has made more than 50 daily

episodes.

Sometimes more than daily, to keep you informed about what's happening and why it matters.

And we're able to do that and to put it out there for free because of support from listeners

like you.

You and everybody else who listens to our shows are the biggest source of financial support

for NPR's member stations.

No matter where or how you hear us every day, the fact is that the stations are the

reason this podcast exists in the first place.

So if you enjoy our podcast, please take a second to give back.

Donate online to support us and your local station by heading to donate.mpr.org slash politics.
