It pays to have friends in high places-literally. Michelle Obama announced today that she will replace her current chief of staff with long-time colleague and friend Susan Sher, making Sher's the third top-notch position in the East Wing held by friends of the first lady. Sher is currently an associate counsel to the president and will take the place of incumbent chief of staff Jackie Norris, who is moving on to become senior adviser of AmeriCorps. It's unclear why the first lady made the switch—perhaps the workings of the administration are not as smooth as they appear. Sher and Michelle Obama worked together at the University of Chicago Medical Center, where Sher was Michelle's boss. She's also counted as a member of Michelle's inner circle traveling with her during the presidential campaign and socializing with her in the White House. All that may be well and good, but the question remains: Is she "in" enough to go on burger runs with the president?
