The Danish Cycling Federation knew, the UCI knew but the *team* dint.
They did ask questions and got answers that satisfied them until it became clearly a lie. They confronted him and he either admitted it or at least dint deny it.
I think this a perfectly reasonable chain of events given the countries involved.

I tell you who I feel sorriest for is the rest of the team and the behind-the-scenes mechanics, physiotherapists,etc who worked so hard for Rasmussen.
