WASHINGTON — Susan Sher, Michelle Obama’s chief of staff, will leave her post in January.
Sher, a longtime Obama mentor, took the helm in June 2009, overseeing the rollout of the first lady’s childhood-obesity initiative and coordinating with the West Wing on Michelle Obama’s role in the elections.
No successor has been named, but Tina Tchen, White House director for public engagement and a big Obama fundraiser, is considered a possible replacement. Sher will stay on to manage the transition.
