Us swimmers quit brazil admitting inventing mugging

I think there may be some confusion here!

It seems you're referring to a recent news story about a group of American swimmers who were involved in a controversy in Brazil. Here's what happened:

On August 5, 2016, Ryan Lochte, Gunnar Bentz, Jack Conger, and Jimmy Feigen, four American swimmers, were involved in an incident at a gas station in Rio de Janeiro, Brazil, after the Olympic Games. The swimmers claimed that they were robbed at gunpoint by masked men while returning to the Olympic Village from a party.

However, Brazilian authorities disputed the swimmers' account, saying that the men had vandalized a gas station and then lied about being robbed. The police investigation found that the swimmers had indeed damaged the gas station's property and had not been robbed.

As a result, the Brazilian authorities charged the swimmers with vandalism and making false statements. The swimmers eventually admitted to making a false report about the incident, and they apologized for their actions.

In the end, the swimmers were fined and had their passports returned. The incident sparked a diplomatic row between the United States and Brazil, with both countries issuing statements expressing disappointment and regret over the incident.

So, to summarize, the American swimmers did not "quit" Brazil, but rather, they were involved in a controversy that led to a false report and subsequent apologies.
