Corruption allegations
Warner has been accused of corruption for repeatedly taking advantage of his position for financial gain.
Via a private family company, Warner owned shares in Simpaul, a travel and holiday company. In a series of exposés during December 2005, the Trinidad and Tobago Express revealed that Simpaul was offering $30,000 packages to the 2006 FIFA World Cup in Germany, which effectively marked up match tickets at a high rate. FIFA's ethics committee criticised the ticket deals, concluding Warner had abused his position to obtain personal benefits and failed to declare his business interests. Warner agreed to sever all family links with Simpaul immediately. However, his son Daryan remained a director of Simpaul throughout World Cup 2006, while his personal assistant remained the company secretary of Simpaul.
FIFA started an investigation and asked their auditors Ernst & Young, to investigate. In a report submitted to FIFA in March 2006, E&Y estimated that Warner's family had made a profit of at least $1 million from reselling 2006 World Cup tickets, that Warner had directly ordered or sold on behalf of the TTFA. Minutes of FIFA's executive committee indicate that in consequence of being found guilty of breaking FIFA's Article 5, a fine of almost $1 million, equal to the expected profiteering, was imposed on the family. Despite numerous reminders from FIFA, only $250,000 has been paid. Andrew Jennings, the presenter of "FIFA's Dirty Secrets", an edition of BBC's Panorama, repeated the allegations in a November 2010 programme during the week Warner and his fellow FIFA Executive Committee members voted to decide the hosts for the 2018 and 2022 World Cups.
Scottish Football Association President John McBeth said Warner asked that monies owed to the TTFF be sent to Warner's personal account. According to McBeth, after Trinidad and Tobago visited Scotland for a friendly match at Easter Road, Edinburgh, on 30 May 2004, Warner asked that the cheque for the game be made out to him. McBeth told Warner, "we don't do that" and noted that Warner also approached other members of the Scottish FA following the game in an attempt to collect money due to the TTFF.
On 10 May 2011, former chairman of the English Football Association, Lord Triesman, accused Warner and several others of asking for compensation in return for votes for England's 2018 World Cup bid. Warner reportedly asked for £2.5 million that would go toward building an education centre in Trinidad. Sir Dave Richards, the chairman of the Premier League, who was present at the meeting, confirmed that the intention of cash for votes was implied, although it was not explicitly stated. However, Warner described the allegations as "a piece of nonsense".
On 26 May 2011 the BBC published an email from Warner to the English FA requesting funds to purchase Haiti's World Cup television rights. The above article also quotes FIFA as denying that Haiti had ever been granted television rights for this competition. This email appears to substantiate a separate charge by Lord Triesman (formally heading the England 2018 World Cup bid) whereby Warner had requested funds from the English to (again) be sent into his personal account so that he could purchase the rights as a humanitarian gesture for the Haitian people. In return, the English bid team could expect his support during the bid process. The total sum that Warner had requested in this instance was in the region of $1.6 million.
In December 2011 Warner said he purchased the television rights for the 1998, 2002, 2006, 2010 and 2014 editions of the FIFA World Cup for Trinidad & Tobago, via a Mexican company. Warner said he purchased the rights for the 1998 FIFA World Cup for one dollar. Warner also said that he refused to endorse Sepp Blatter in the 2011 FIFA Presidential election despite being offered the rights to the 2018 and 2022 World Cup, again for a nominal fee. Warner further alleged that he was offered other "inducements" to develop football in the Caribbean. Warner says he used the revenue from selling on the rights to develop football in the Caribbean.
In February 2012 the TTFF said that funds for Haiti donated following the 2010 earthquake were paid into a bank account controlled by Warner. FIFA subsequently froze funding to the TTFF until it received an explanation. FIFA is also withholding Warner's pension. Warner later suggested that the allegations were a conspiracy, saying that "I have nothing to answer to anybody. Who wants to make allegations, make allegations. Ask yourselves, as objective members of the media: 'Why now...?' And after you get why now, just join the dots and see."
On 19 April 2013, the CONCACAF Integrity Committee, headed by David Simmons, former Chief Justice of Barbados, alongside retired United States District Court Judge Ricardo Urbina and ex-PricewaterhouseCoopers partner and auditor Ernesto Hempe, issued a report accusing Warner and his former cohort Chuck Blazer of mismanagement and massive fraud. Warner is alleged to have concealed his ownership of the land on which CONCACAF's $25 million Joao Havelange Centre of Excellence was built, which made him the effective owner of the building. Warner's initial public reaction was defiant: "As far as I am aware it is baseless and malicious. I left CONCACAF and turned my back on football two years ago. Since then I have had no interest in any football-related matter."
In May 2015, Warner was indicted by the United States Department of Justice and an arrest warrant issued for him and other FIFA officials. Warner and the others were accused of "wire fraud, racketeering and money laundering".
Warner handed himself into Trinidad police in May and was bailed pending extradition to the United States.
The following week, he said publicly that he had documents linking the outcome of the 2010 Trinidad and Tobago general election with FIFA finances and himself.
Warner made the statements in a paid national television political broadcast, saying that his life was in danger, that he had given the documents to lawyers, and, "I will no longer keep secrets for them who actively seek to destroy the country."
After the US formally requested Warner's extradition in July 2015, he appealed against the procedure, represented by a strong legal team. After more than two years of deliberation, on 28 September 2017 High Court judge James Aboud ruled against the suit, allowing the extradition process to proceed, while granting Warner and his legal team 28 days to appeal the decision. On 2 November 2017 Warner's attorneys filed an appeal. On 2 March 2018, Justice of Appeal Mark Mohammed granted Warner an appeal of Aboud's ruling, to be heard in November 2018—effectively postponing any possible extradition until some time after the hearing.
In mid-June 2019 a three judge Appeal Court dismissed Warner's claim that the order against him contravened Trinidad and Tobago's Extradition Act. However, the Court granted him a 21-day stay before extradition can proceed, for a direct appeal to the Judicial Committee of the Privy Council.
In July of that year, a United States court entered a default judgement against Warner in a civil lawsuit filed by CONCACAF when Warner failed to appear, ordering Warner to repay US$79 million that he had fraudulently obtained from CONCACAF.
In April 2020, additional information was revealed in an unsealed indictment, alleging that Warner had "received $5 million in more than two dozen separate wire transfers to vote for Russia to host the 2018 soccer championship. The wire transfers were sent from 10 different shell companies in Cyprus, Anguilla and the British Virgin Islands and then cleared through correspondent U.S. bank accounts."
A constitutional challenge to his extradition began 29 May 2025. On 23 September 2025, the high court in Trinidad rejected Warner's extradition.
