He's now facing an FBI investigation brought on by WADA. I don't think they're going to be intimidated.
As for the people talking about what happens if Nike pulls out of track and field, they should be asking what happens if Nike doesn't pull out...and there continue to be these scandals, and, eventually, there isn't any track and field any more, because nobody wants to cover it, because nobody wants to sponsor it, because all anyone hears about regarding track is drugs.
Nike is a cancer that must be cut out, or the patient is going to die. Before we talk about the Russians, the Kenyans, and others, we need to clean our own house. Track and Field doesn't need Nike. There are very few athletes making a living in track anyway, and it doesn't cost that much to do the selection meets which is USATF's only charter under the Amateur Sports Act. Just get rid of them, under force of decertification, if necessary.
