Senator Flávio Bolsonaro is a Brazilian presidential candidate. Brazil's Supreme Court is investigating him for corruption.

The investigation also covers money laundering and currency evasion. Court documents unsealed Friday revealed details of the probe.

The probe centers on financing for a film. The film is about his father Jair Bolsonaro.

Jair Bolsonaro is a former Brazilian president. Investigators say Flávio Bolsonaro received $12 million from a banker.

Reports identify the banker as Daniel Vorcaro. Authorities are checking if public money was used.

They are also checking if funds went into a US account. A lawyer linked to Eduardo Bolsonaro reportedly manages that account.

The investigation comes weeks before Brazil's presidential election. Reports say Flávio Bolsonaro is polling closely with President Lula da Silva.

Lula da Silva is Brazil's current president. His campaign now faces fallout from this investigation.
