Thanks for all of your comments in response to last night's question. Tonight we want to know what you think about Marion Jones, the U.S. Olympic Gold Medalist who today admitted to using performance enhancing steroids during the 2000 Olympics and lying to federal investigators during a subsequent investigation.
Do you suspect most record-breaking athletes use illegal performance enhancing drugs? Submit your comments below and we'll read some of them during the show. Also tonight: a closer look at drug testing for athletes -- we're Keeping Them Honest. Plus, Marion Jones, in her own words. See you at 10p.m. ET.
