The anonymous sales clerk accused of racism by Oprah Winfrey is fighting back by way of a newspaper interview in which she says the media tycoon is lying about an incident that occurred in a Swiss store recently, and she says as a result, she has been thrust into a media-infused "nightmare” that has left her feeling "powerless." "I don’t know why she is making these accusations. She is so powerful, and I am just a shop girl," the sales clerk told the Swiss newspaper SonntagsBlick, according to a translation from London’s Daily Mail.
