Paragraph- Sent 1: (CNN) -- Champion cyclist Lance Armstrong said Wednesday the U.S. Anti-Doping Agency intends to "dredge up discredited" doping allegations against him in a bid to strip him of his seven Tour de France victories.
Sent 2: The Washington Post said it received a copy of a 15-page agency letter sent Tuesday to Armstrong and several others.
Sent 3: As a result of the allegations, Armstrong was immediately banned from competing in triathlons, a sport he took up after retiring from professional bicycling, the newspaper reported on its website.
Sent 4: Armstrong, as he has in the past, said he has never engaged in doping.
Sent 5: "Unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one," Armstrong said on his website.
Sent 6: "That USADA ignores this fundamental distinction and charges me instead of the admitted dopers says far more about USADA, its lack of fairness and this vendetta than it does about my guilt or innocence."Sent 7: Justice Department prosecutors in February said they closed a criminal investigation after reviewing allegations against Armstrong.
Sent 8: They had called witnesses to a federal grand jury in Los Angeles, but they apparently determined they lacked evidence to bring a charge that Armstrong used performance-enhancing drugs.
Sent 9: Armstrong was accused of using such drugs by other riders, but never failed a drug test.
Sent 10: "These are the very same charges and the same witnesses that the Justice Department chose not to pursue after a two-year investigation," Armstrong said Wednesday.
Sent 11: According to the Post, the U.S. Anti-Doping Agency alleged it collected blood samples from Armstrong in 2009 and 2010 that were "fully consistent with blood manipulation including EPO use and/or blood transfusions."Sent 12: The allegations were previously unpublicized, according to the Post.
Sent 13: Opinion: Why fans shouldn't forgive Armstrong The letter says Armstrong and five former cycling team associates engaged in a doping conspiracy from 1998 to 2011, the Post reported.
Sent 14: Riders will testify that Armstrong used EPO, blood transfusions, testosterone and masking agents, and that he distributed and administered drugs to other cyclists from 1998 to 2005, the Post quoted the letter as saying.
Question: What allegations from 2009-2010 were previously unpublicized, according to the Post?.
