When the Senate goes on recess at the end of this week, President Obama should appoint Elizabeth Warren to direct the Consumer Financial Protection Bureau. By making a recess appointment, the president can name the best qualified leader to head the new agency, while demonstrating he’s willing to stand up to Republican obstruction and Wall Street pressure. He’ll earn plaudits not only from the base of the Democratic Party that adores Warren but also from independent voters, who will be thankful for an advocate for consumers willing to stand up to the Wall Street lobby.
