During the Presidential transition of Barack Obama, at least five candidates were interested in the position, including Obama campaign foreign policy advisor Eric Lynn, Hillary Clinton campaign Jewish coordinator Josh Kram, Robert Wexler foreign policy advisor Halie Soifer, Ron Klein legislative director Mira Kogen Resnick, and Amtrak deputy general counsel Jonathan Meyer. The post was initially co-held by Susan Sher, chief of staff to the First Lady, and Danielle Borrin, who held the position of Special Assistant for Intergovernmental Affairs and Public Engagement to Vice President Joe Biden. Sher left the White House in January 2011.
