US anti-doping chief accuses IOC of 'threats' over 2034 Salt Lake Olympics

US anti-doping chief Travis Tygart accused Olympic bosses of "stooping to threats" after they awarded the 2034 Winter Games to Salt Lake City on Wednesday but warned US authorities to get in line.

The success of Salt Lake's bid was a foregone conclusion given the Utah city, which hosted the Games in 2002, was the only candidate.

But in a dramatic twist shortly before members of the International Olympic Committee approved the bid by 83 votes to six, Olympic chiefs warned the decision could be reversed if US lawmakers and the US Anti-Doping Agency (USADA) were not brought into line.

John Coates, chairman of the IOC's legal commission, said the host city contract confirming Salt Lake's right to stage the Games had been altered to allow the IOC to take them away if US authorities did not respect the "supreme authority" of WADA.

Speaking in Paris ahead of the opening of the Games on Friday, Coates said it was "a must, and I stress the word must" for the US authorities to respect WADA.

"The IOC has reinforced the current language of the Olympic host contract in order to protect the integrity of the international anti-doping system and to allow the IOC to terminate -- to terminate -- the Olympic host contract in cases where the supreme authority of the World Anti-Doping Agency... is not fully respected or if the application of the World Anti-Doping code is hindered or undermined," Coates said.

The warning stunned seasoned observers of the IOC and sports politics.

USADA has been a vocal critic of WADA over the past decade.

Tensions spiked this year after reports in April said 23 Chinese swimmers had tested positive for a banned substance ahead of the 2021 Tokyo Olympics, but were cleared to compete at the Games.

Tygart has consistently accused WADA of covering up the cases, which China blamed on unintentional food contamination.

Eleven of the 23 Chinese swimmers are in Paris.

- 'Sport lapdog' -

In an angry statement, Tygart again condemned WADA's handling of the case of the Chinese swimmers and lashed out at the conditions of the agreement for Salt Lake to host in 2034.

"It is shocking to see the IOC itself stooping to threats in an apparent effort to silence those seeking answers to what are now known as facts," he said.

"It seems more apparent than ever that WADA violated the rules (over the Chinese swimmers) and needs accountability and reform to truly be the global watchdog that clean athletes need.

"Today's demonstration further showed that as it stands today, WADA is just a sport lapdog, and clean athletes have little chance."

WADA has angrily rejected the criticism from USADA, threatening legal action against the body.

WADA, which has also faced criticism beyond the United States, welcomed Wednesday what it called unequivocal support.

Its president Witold Banka said there had been "politicisation of anti-doping within the US".

Coates said both the United States Olympic and Paralympic Committee (USOPC) and the state of Utah had agreed to the reworded host city contract.

"We are committed to fostering WADA's authority as (it) is crucial for the opportunity to provide clean sport for athletes and give them confidence that they can be protected," USOPC chairman Gene Sykes said.

"Our view is that this is of paramount importance and we take their concerns very seriously."
