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.

Paragraph- Sent 1: A supporter of Cavaignac and of the parti de l'Ordre, Tocqueville, however, accepted an invitation to enter Odilon Barrot's government as Minister of Foreign Affairs from 3 June to 31 October 1849.
Sent 2: There, during the troubled days of June 1849, he pleaded with Jules Dufaure, Interior Minister, for the reestablishment of the state of siege in the capital and approved the arrest of demonstrators.
Sent 3: Tocqueville, who since February 1848 had supported laws restricting political freedoms, approved the two laws voted immediately after the June 1849 days, which restricted the liberty of clubs and freedom of the press.
Sent 4: This active support in favor of laws restricting political freedoms stands in contrast of his defense of freedoms in Democracy in America.
Sent 5: According to Tocqueville, he favored order as "the sine qua non for the conduct of serious politics.
Sent 6: He [hoped] to bring the kind of stability to French political life that would permit the steady growth of liberty unimpeded by the regular rumblings of the earthquakes of revolutionary change.''Sent 7: Tocqueville had supported Cavaignac against Louis Napoleon Bonaparte for the presidential election of 1848.
Sent 8: Opposed to Louis Napoleon's 2 December 1851 coup which followed his election, Tocqueville was among the deputies who gathered at the 10th arrondissement of Paris in an attempt to resist the coup and have Napoleon III judged for "high treason", as he had violated the constitutional limit on terms of office.
Sent 9: Detained at Vincennes and then released, Tocqueville, who supported the Restoration of the Bourbons against Napoleon III's Second Empire (1851-1871), quit political life and retreated to his castle (Chateau de Tocqueville).
Sent 10: Against this image of Tocqueville, biographer Joseph Epstein has concluded: "Tocqueville could never bring himself to serve a man he considered a usurper and despot.
Sent 11: He fought as best he could for the political liberty in which he so ardently believed - had given it, in all, thirteen years of his life [....] He would spend the days remaining to him fighting the same fight, but conducting it now from libraries, archives, and his own desk."Sent 12: There, he began the draft of L'Ancien Regime et la Revolution, publishing the first tome in 1856, but leaving the second one unfinished.
