National officials for Australia and China are jumping into the fray as a feud between swimmers Mack Horton and Sun Yang continues to boil.
The Chinese Swimming Association on Monday asked Horton to apologize for his "inappropriate words" after he labeled Sun a "drug cheat" — a reference to Sun's three-month 2014 suspension over banned heart medication.
Australia's Olympic Committee, hours later, shot back in Horton's defense, saying he was speaking out in support of clean athletes, and wished him luck.
