Accusations in 2005 that he had engaged in blood doping in 1999 were denied by Armstrong and disputed in 2006 by an International Cycling Union (ICU) investigation, which found no evidence to support the charges. Subsequently, additional accusations were made regarding Armstrong and his team, but he continued to deny the charges until 2013, when he finally admitted to doping. In 2012, after the U.S. Anti-Doping Agency (USADA) said it had clear evidence of doping and released a detailed and extensive report covering the years of his Tour de France victories, the ICU agreed with USADA's decision to strip Armstrong of his results since 1998 and bar him from the sport for life. In 2013 he was stripped of his Olympic medal, and in 2018 he agreed to pay $5 million to settle claims he had defrauded the United States Postal Service (his cycling team's sponsor).
