A guest at former President Barack Obama’s 60th birthday bash said he was forced to delete Instagram photos he posted of himself at the star-studded event on Martha's Vineyard Saturday night. Rapper Trap Beckham and his manager, TJ Chapman, posted Instagram photos of the food and décor at the event, as well as themselves smoking marijuana, which is legal in Massachusetts, but the photos were later deleted under the event’s photography ban, the New York Post reported.
