The US Olympic Committee (USOC) and USA Swimming have sanctioned four swimmers with varying bans for fabricating a story about being robbed at gunpoint during celebrations at the Rio 2016 Olympics, in order to cover up misbehaviour at a petrol station. Three of the four took gold in the 4x200m freestyle at the Rio Olympics and one took gold in the 4x100m, which they will be allowed to keep, after the Fédération Internationale de Natation (FINA) decided that no further action was needed.

Ryan Lochte has been sanctioned with a ten-month ban, which means he will miss the 2017 FINA World Championships, which take place in Budapest, 14-30 July. He will also forfeit USOC and USA Swimming medal funding for his Rio 2016 gold, which is understood to be worth US$100,000, and will perform 20 hours of community service.

Gunnar Bentz, Jack Conger (4x200m) and James Feigen (4x100m) have been sanctioned with a four-month ban. Bentz will also have to perform ten hours of community service, due to violating a 1am USA Swimming Olympic Village curfew placed on U21 athletes.
