President Obama’s top economic adviser, Alan Kruegman, is leaving his White House job to teach at Princeton University, the White House Press Office announced today.

“I am deeply grateful to President Obama for the opportunity to serve twice in this Administration, and for the chance to do what I could to help the Nation recover from the worst economic crisis since the Great Depression, and put policies in place that create good jobs and help reignite a rising, thriving middle class,” Krueger, chairman of the Council of Economic Advisers, said in a statement.  “It has been one of the highest privileges of my life to serve the American people.”

Krueger has been the face of Obama’s economic policy, issuing the White House analysis of each month’s jobs report and defending the administration’s record on a regular basis, including throughout the campaign season. He’s also been “the driving force behind many of the economic policies that I have proposed,” Obama said today.

“And while we have more work to do, today our economy is improving – thanks, in no small part, to Alan’s efforts. I want to thank Alan for his service and wish him the best of luck as he returns to Princeton,” Obama said in his statement on Krueger’s departure.

That “more work” line is a Krueger staple: he’s written it in several recent posts on the jobs report, as The Weekly Standard noted. Another one: don’t “read too much” into the jobs numbers, Krueger warned Americans dozens of times.
