During daughter Victoria's junior year of high school she was up for expulsion by the Ross School in East Hampton, New York for reportedly smoking marijuana with friends on campus. Victoria and her family chose to withdraw from the school before expulsion could be placed on her academic record. Victoria was also the subject of a controversial video posted to YouTube concerning public display of drugs and racist language. Victoria used the word "nigger" and was shown rolling a joint while on video chat with her friend. Once brought to light, the video was soon removed.
