The United States Anti-Doping Agency has opened an investigation into possible tampering with anti-sorting rules in an attempt to avoid a major international doping scandal.

The U.S. Anti-dopers group announced Tuesday it will launch an investigation with the aim of determining if the anti-testing rule violations were the result of deliberate, systematic and/or intentional misconduct.

The probe comes as USADA moves to reclassify some of its anti-bodies and conduct more rigorous testing to be able to catch the highest-level athletes.USADA is conducting the investigation in cooperation with the American Anti-Bias Coalition, the National Association of Conforming Sports, and the National Football League, which has also been cooperating with the U.N. body.

It said it will use “every tool available” to try to determine whether the anti-[sorting] rule violations could be intentional.USATODAY SPORTS: USADA investigation into potential tampering in Anti-Sorting rule violations – article In its statement, the USADA said it intends to conduct a thorough investigation into whether the violations could have been the result in deliberate, systemic and/ or intentional misconduct or if they were a result of a systematic, systematic or intentional abuse of power.

The investigation will be conducted by two outside attorneys and will be led by an outside investigator who will be appointed by the Anti-sort Task Force.

It added that it intends “to cooperate fully” with the task force and that it will “conduct its own investigation to ensure the fullest possible scope of its inquiry.”

The Anti-Sports Anti-Corruption Committee of the United States Olympic Committee (USOC) and the Antiā€“Corruption and Anti-Kickback Compliance Unit of the World Anti-Fraud Agency (WADA) have also been appointed to lead the investigation.USOC Vice President and Chief Executive Officer Mark Adams said the probe would be overseen by the Office of the Inspector General and the Office for Civil Rights and Civil Liberties, both of which have jurisdiction over anti-abuse rules violations.

“This is a first step to bring an end to this investigation and allow for full accountability,” Adams said in a statement.

The USOC also announced that it had begun an internal review of the US Anti-Drug Program, which it said had been unable to respond to its recommendations in the first six months of the AntiSorting investigation.

The review will be completed in the coming weeks, USOC General Counsel Mark Schilling said.

“We are determined to bring these matters to a conclusion quickly, and we are also committed to working with our sport and federal partners to ensure that the investigation is conducted in an open, transparent and ethical manner,” Schilling added.USAC’s investigation is one of the most serious in recent years, with dozens of athletes being cleared of a crime.

Last year, the Anti Sorting Task Force cleared six athletes of a misdemeanor charge of “intentionally and knowingly causing an adverse environmental impact” for using an anti-patterning test to test a urine sample from a competitor who had tested positive.

USADA also cleared the American Association of Pro Boxing and Greco-Roman Heavyweight Titleholders of using an antifreeze test to check for the presence of an anti doping substance on their boxer’s gloves.
