On the July 18 edition of ABC’s “World News Tonight,” senior White House correspondent Jake Tapper interviewed Elizabeth Warren about the new Consumer Financial Protection Bureau, which begins operations this week, and cited the Democracy essay in which she first introduced the idea for the agency. Earlier that day, President Obama had tapped former Ohio Attorney General Richard Cordray to head the CFPB.

Warren proposed the creation of the agency in a 2007 Democracy essay, “Unsafe at Any Rate.” Speaking with Tapper, she expressed optimism about the bureau’s future and discussed her role in its founding. “Nobody’s responsible to the American consumer, no one’s looking out for American families; we started that,” she said.

Tapper noted that the agency sprang from her piece in the Spring 2007 issue of Democracy. Warren replied, “Of all the ideas that get published in… journals like that, not so many make it into law.”
