I just secured a statement from Andrew Williams, Treasury’s Deputy Assistant Secretary for Public Affairs, about Timothy Geithner’s views on Elizabeth Warren. This has been a raging controversy since it was reported last night that Geithner would potentially move to block Warren’s appointment to head the Consumer Financial Protection Bureau due to friction between the two in the past. Here’s the statement in full:

“Elizabeth Warren has been a driving force behind the creation of the consumer financial protection bureau, and we have worked very closely with her over the past year and a half to make that idea a reality.

“Given her strong leadership on consumer protection, Secretary Geithner believes that Elizabeth Warren is exceptionally well qualified to lead the new bureau, and, ultimately, that’s a decision the President will have to make.”

Geithner pointedly punts this to the President, rightly stating that it’s his responsibility to name a head of the bureau. He does not come out and endorse Warren, but I wouldn’t expect him to.

What’s important here is the overall dynamic in the past 24 hours. Since the initial report in the Huffington Post, we now have Michael Barr saying that Warren is exceptionally well-qualified, David Axelrod saying she’s a candidate to lead the bureau and now Geithner saying something similar. Basically, this has become a test for the Obama Administration, and the base of the party is watching very closely.

Obama could end the speculation by immediately naming Warren, who invented this concept and has been the most dogged protector of consumers in America for the last decade, to run this bureau. It would set the bureau on a course as a powerful regulator for the next several decades, and would put it on a footing with the likes of the FDA, the CPSC and other consumer protection agencies. And it would have someone in charge who, unlike those other agencies in past Administrations, wouldn’t have the taint of once working for the industries they regulate. Because of the wide discretion in the bill, Warren could shape the agency as she sees fit. Just because there is no requirement for a “plain vanilla” contract on financial products, in readable English for consumers, doesn’t mean the chief regulator couldn’t make a rule mandating one. And that’s just one example.

…by the way, if this opinion means anything, Wall Street would be happier with Michael Barr running the CFPB than Warren.

UPDATE: One thing I just learned: until the Senate confirms a director of the consumer protection bureau, it will be run by… Tim Geithner.
