The Posto da Torre is a busy gas station in Brazil’s government seat of Brasilia. Before 2013, Posto da Torre (Tower Gas Station) was just one of many of gas stations in the capitol. After 2013, Posto da Torre became the symbol of corruption in Brazil.

A drug investigation by police into a money exchange shop located on the Posta da Torre property revealed that billions of dollars secretly skimmed from the accounts of Petrobras, Brazil’s state oil enterprise, as well as construction companies, were moved into the hands and accounts of Brazil’s most prominent politicians. In fact, over 100 of Brazil’s top politicians have been implicated in what is today called Operation Car Wash, known in Portuguese as Operação Lava Jato.

One of the more well-known names caught up in web of Operation Car Wash is former mayor of Rio de Janeiro, Eduardo Paes, whose name has appeared on lists of people receiving payments from construction companies, presumably related to the development projects for the 2016 Rio Olympics. According to this post from Inside the Games, Paes is alleged to have received over USD5 million from from engineering giant Odebrecht.

Paes, who ended his role as mayor at the end of 2016, has denied wrongdoing, calling allegations “absurd”.

Former Brazil President, Henrique Cardoso is also under investigation for taking bribes from Odebrecht, has spoken recently about Operation Car Wash and its significance. “Car Wash has played a very important role in Brazil because it lifted the lid, which was necessary. But that will not resolve things immediately. It is a process,” he said in this Reuters article. “How do you change a culture? With time and by setting a good example – there is no other way.”

An interesting aside: there is no car wash in Posto da Torre. As The New York Times cheekily point out, the closest this Brasilia gas stop has to a car wash is a laundromat. At any rate, it is money that gets washed, not cars. When politicians will come clean is anyone’s guess.
