Jop! I'm Isaac Dauver and this week I'm Radio Atlantic I sat down with Tom Steier.

You may know Steier now as one of the billionaires running in the Democratic presidential

race, but he's been funding grassroots organizing efforts for years, first on climate change,

then on mobilizing young people, and in these past two years on impeachment.

He's brought us to the brink of nuclear war, obstructed justice at the FBI, and in direct

violation of the Constitution, he's taken money from foreign

governments and threatened to shut down news organizations that report the truth.

If that isn't a case for impeaching and removing a dangerous president, then what is our government become?

That's Tom Steyer in an ad he started running in October of 2017.

His group Need to Impeach spent millions of dollars running ads across the country over the last two years,

and it claims now over 8 million members,

which for comparison's sake is 3 million more than the NRA.

Stier was out front on impeachment, and with his money and organizing,

he's been a real factor in making impeachment a constant topic in politics,

long before Trump called the president of Ukraine and asked for a favor.

The two of us were in Los Angeles for Thursday's Democratic debate.

With the House voting on impeachment the day before, we wanted to talk with him about this moment and what it meant in history.

So we asked him to meet me at the Richard Nixon Presidential Library, about an hour outside

of town in Yorbilinda.

This was another weird day in the life of being a political reporter.

Richard Nixon, on the day the President of the United States was being impeached, with the

guy who helped lead the impeachment campaign.
