Lance Armstrong stepped down as chairman of the Livestrong cancer support charity he founded. Nike dropped him over the doping scandal that will likely cost him his seven Tour de France titles. Yet, Livestrong donations have actually increased despite the scandal. Anheuser-Busch is also ending its relationship with Armstrong, as is Trek. Oakley Inc, the sunglasses brand said it was reviewing the reports into the cyclist's conduct and awaiting a final decision from the sport's international authorities. A Radio Shack spokesman said the electronics retailer remains a sponsor of Armstrong and Livestrong.
