President Obama has reappointed James Willis to one of the trade slots on CPAC. See http://www.whitehouse.gov/the-press-office/2012/04/16/president-obama-announces-more-key-administration-posts
Jane Levine of Sotheby's continues in another trade slot despite the fact that the Department of State and its Cultural Heritage Center have funded Heritage Watch, the NGO that has been at the forefront of pressing the US and Cambodian governments to seek repatriation of a Khmer statue that was due to be auctioned off by Sotheby's. See http://culturalpropertyobserver.blogspot.com/2012/04/government-supported-by-archaeological.html
One other trade slot remains vacant.
