Via his Facebook page, Kevin James let us all know that he performed his magic at the Presidential Halloween party last night. You'll see him peeking out in the back of the photo above from the NY Times. According to the article:
Mr. Obama did not dress up, wearing just a sweater and slacks — perhaps his costume was president of the United States. Mrs. Obama played the role of Cat Woman. The White House press secretary, Robert Gibbs, dressed as Darth Vader, and the United States ambassador to the United Nations, Susan E. Rice, went as the Disney character Goofy.
According to Kevin, "Highlights of the evening was meeting the Obama Family and the Rahm Emanuel family. It was a very magical evening."
