"FILE - This Dec. 4, 2011 file photo shows ""Sesame Street"" character Elmo and puppeteer Kevin Clash arrive at the Kennedy Center for the Performing Arts for the Kennedy Center Honors gala performance in Washington. Clash has taken a leave of absence from the popular kids' show following allegations that he had a relationship with a 16-year-old boy. Sesame Workshop says Kevin Clash denies the charges, which were first made in June by the alleged partner, who by then was 23. In a statement issued Monday, Nov. 12, 2012, Sesame Workshop says its investigation found the allegation of underage conduct to be unsubstantiated.  (AP Photo/Kevin Wolf, file)"
