Thanks to the Supreme Court’s Citizens United ruling, a trove of so-called "dark money" was about to be unleashed. Two activists prepared to seize the moment.

The Supreme Court’s decision in the 2010 Citizens United case transformed the world of politics. It loosened restrictions on campaign spending and unleashed a flow of anonymous donor money to nonprofit groups run by political activists.

In the months before the ruling dropped in January of that year, a group of conservative activists came together to create just such an organization. Its mission would be to, at the time, block then-President Barack Obama’s pet initiatives.

The activists included Federalist Society leader Leonard Leo and his ideological soulmate, a hard-edged activist named Virginia Thomas, the wife of Supreme Court Justice Clarence Thomas.

“Ginni really wanted to build an organization and be a movement leader,” said a person familiar with her thinking at that time. “Leonard [Leo] was going to be the conduit of that.”

She also had a rich backer: Harlan Crow, the manufacturing billionaire who had helped Thomas and her husband in many ways, from funding luxury vacations to picking up tuition payments for their great-nephew.
