WASHINGTON-- President Obama on Monday hinted that he may be switching leadership on his White House economic team.

John Harwood asked Obama at a "town hall" here: We're coming up to the midterm election; have you asked your Treasury secretary, Tim Geithner, and your top economic adviser, Larry Summers, to stay with you through the end of your term? Or might you make some changes?"

Said Obama, "Well, look, I -- I have not made any determinations about personnel. I think Larry Summers and Tim Geithner have done an outstanding job, as have my whole economic team. This is tough, the work that they do. They've been at it for two years. And, you know, they're going to have a whole range of decisions about family that'll factor into this as well. But the bottom line is -- is that we're constantly thinking, is what we're doing working as well as it could? Do we have other options and other alternatives that we can explore?"
