From the USADA letter to Lance Armstrong:
García del Moral left the Postal team following the 2003 season under circumstances that remain unclear. García del Moral continued to work with athletes at the Instituto de Medicina del Deporte, a Valencia health clinic that specializes in sports injuries and performance-enhancing treatments. Staff members say the center, part of a network that includes several others in Spain, is managed by the regional government and works often with professional athletes, including cyclists, track-and-field athletes, soccer and tennis players, providing advice on nutrition and training regimes and top-class fitness equipment.
Why is such a doctor allowed to work with professional athletes at a government funded health clinic
He didn't stop doping athletes after leaving USPS.
An excerpt from Paul Kimmage's interview with Floyd Landis:
Q: How did you manage your doping in ’05? The Wall St Journal piece said: Mister Landis said he hired a Spanish doctor in Valencia to take transfusions and paid one person $10,000 to make two separate deliveries of half-litre bags of blood during the 2005 Tour de France.
A: In 2004, the Postal Service got rid of Luis Garcia Del Moral, who was the team doctor, and I knew that he was often in charge of the logistics of doing transfusions and things like that, so I just contacted him and asked if he would do it for me. So I paid him to do it.
Q: Del Moral?
Q: You paid Del Moral?
Q: Did that ‘work’?
A: Did it work? Yeah, the reason that I was not as good in 2005 as I was in 2004 or 2006 was because I had surgery that winter and wasn’t walking for weeks and it took a while to get back in shape. So drugs or no drugs weren’t going to change that. I did the same thing in 2004 and 2005 and 2006; the one variable was that I had my hip issues to deal with and therapy and things like that. I mean, in all of the Tours I did exactly the same amount of blood (transfusing) except the first one (2002); the first one I did one transfusion which is 500 millilitres and the next four I did 1000 militaries each, three separate times in 2006, because it was easier to maintain the continuous blood parameters that were being checked. But it ended up being the same total volume that I added so…yeah, Del Moral, in spite of denying that he ever saw any doping, like everybody does, that was all he really did.
