What happened
This week, Brazil Supreme Federal Tribunal (STF) Justice André Mendonça — overseeing the Banco Master case, a São Paulo bank-fraud investigation in which banker Daniel Vorcaro is in custody — unsealed a Federal Police report on alleged WhatsApp messages recovered from Vorcaro’s phone between Vorcaro and a device attributed to fellow Justice Alexandre de Moraes, and asked Prosecutor General Paulo Gonet to comment. On Thursday, de Moraes asked STF Chief Justice Edson Fachin to investigate Mendonça for abuse of authority, alleging administrative misconduct, usurpation of police authority for political and personal motives, and a loss of impartiality, and seeking to place the matter under the court’s existing “fake news” inquiry opened in 2019. On Friday, Fachin declined to fold the complaint into that inquiry, assigned it to himself, gave Mendonça and Gonet five days to respond, and said he would conclude the “fake news” inquiry, promising a “firm, proportional, and rigorous response.” Speaking at the presidential palace with President Luiz Inácio Lula da Silva, Fachin said the facts were being investigated under the Constitution and the law and that no authority stands above the Constitution. Lula said no one may use their position for personal gain and that everyone must be subject to the same procedures, without naming de Moraes.
Sourcing check · Mostly on the record · 2 articles
1 of 2 articles cite a named source for the story. It started with unnamed sources; a named source appeared 3 hours later.
What these terms mean and how they're counted
- On the record · names a source 1 of 2
- On the record means the article cites a source by name for the story's main claim: a person, or an institution speaking officially, such as a company statement or a named agency's spokesperson. The opposite is an unnamed source. The count is how many of the counted articles cite at least one such source; the names are everyone named across them, each once however the articles spell it. Here: André Mendonça, Edson Fachin and Alexandre de Moraes
- Primary evidence · cites a document or data 1 of 2
- Primary evidence means the article cites a record you could check yourself: a court filing or ruling, a dataset or report, a recording or transcript, an official statement or press release, market data. A quote is not a document. The count is how many articles cite one. Here: police report, court filing
- Credits another outlet 0 of 2
- The article says the story comes from another outlet's reporting (“first reported by Reuters”). Those articles relay the story; they are not independent confirmation. Here: Each article presents its own reporting.
- Unnamed sources 0 of 2
- The main claim is attributed to people who are not identified: “people familiar with the matter”, “officials said”. The count is how many articles do this.
- How it developed
- When the first report landed and whether it named anyone; when the first named source and the first document appeared. Here: First report Sep 4, 15:17 UTC by Bloomberg, with no named source. First named source 3 hours later, from Breitbart. First document 3 hours later, from Breitbart (police report).
- Not counted 0
- Opinion, analysis and video pieces, and articles too short to assess. Every count above is out of the counted articles. An article republished under a new headline is one article.

Omitted — what each side leaves out
Unpacked
Left-leaning coverage never reports that one justice formally accused another of abuse of authority after a police report on alleged banker messages was unsealed. It says only that Banco Master shakes the court and could alter its balance of power. Right-leaning coverage reports that Justice Alexandre de Moraes demanded an investigation of Justice André Mendonça for "abuse of authority" after Mendonça released a Federal Police file on alleged chats with detained banker Daniel Vorcaro. Chief Justice Edson Fachin then forwarded the complaint to his own desk rather than into the fake-news inquiry. Right-leaning coverage is simply more complete on who accused whom.
Right-leaning coverage describes the episode as a "civil war" inside the court. Left-leaning coverage uses none of that language and speaks only of a crisis that could shift institutional power.
What did the alleged messages between de Moraes and the detained banker actually say?
Bottom line
Bloomberg never names de Moraes or Mendonça; it frames Banco Master only as a court crisis that might change the balance of power, not as one justice's formal request to investigate a colleague over unsealed banker chats.
The receipts — 5 facts one side's coverage lacks
- Justice Alexandre de Moraes demanded an investigation of Justice André Mendonça for abuse of authority
- Chief Justice Fachin gave Mendonça and Prosecutor General Gonet a five-day deadline to respond
- President Lula said no one can use their position for personal gain
- Chief Justice Fachin vowed to conclude the fake news inquiry
- The Banco Master case has expanded to corruption allegations linked to the PCC gang
The Left View
Left-leaning coverage, represented here by Bloomberg, frames the Banco Master case as shaking Brazil’s Supreme Court and motivating a crisis that “could alter its balance of power,” casting the episode as an institutional shock to the court’s internal equilibrium rather than as a personality clash.
The Right View
Breitbart describes de Moraes as a “Dictator-Judge” who triggered a Supreme Court “civil war” after the police report was unsealed, presenting his complaint as an attack on a colleague who exposed alleged messages with an “arrested banker accused of corruption.” It says de Moraes sought to route that complaint through the “fake news” inquiry he has, in the outlet’s words, used since 2019 “to justify a pervasive persecution and censorship campaign against conservative voices in Brazil — including former President Jair Bolsonaro.” The piece also ties the underlying bank case to alleged links with the Primeiro Comando da Capital (PCC), a U.S.-designated terrorist organization, and highlights Fachin’s refusal to use that inquiry plus Lula’s remarks that did not name de Moraes.
Our Take (balanced)
The left’s strongest argument, on the coverage provided, is institutional: Bloomberg’s claim that the case “could alter” the court’s “balance of power” treats the clash as a threat to the STF’s internal equilibrium, not a mere spat between two justices. The right’s strongest argument is procedural and evidentiary: a justice overseeing a corruption case unsealed alleged communications between another sitting justice and a detained banker, after which the named justice sought both a colleague’s investigation and placement of that complaint inside an inquiry long associated with his own political-speech enforcement — a sequence Breitbart presents as self-protection. The central unresolved tension is whether unsealing those messages was lawful transparency in a fraud probe or an abuse of authority that breached impartiality — and whether de Moraes’s counter-complaint defends the court’s integrity or aims to contain scrutiny of himself.
