ANC heavyweights including Ayanda Dlodlo, Kebby Maphatsoe and Lerema Kekana faces possible fraud charges into a botched broadband project.
According to the Sunday Times the three scored millions of rands from a botched broadband project for the City of Johannesburg while its costs more than doubled to nearly R1.7 billion.
Dlodlo is a public service and administration minister, Maphatsoe is deputy defence and military veterans minister Kebby, while Kekana is a former diplomat.
The Sunday Times reported that the involvement of the trio in the project is being investigated by the police and the US Department of justice has also shown an interest in the case.
The newspaper said the police are investigating the possibility of fraud and corruption in the contracts, which involve multinational telecommunications giant Ericsson.
A report by Nexus Forensic Services and affidavits by city officials allege that mismanagement and deception compromised the project to provide Johannesburg with cheap broadband services.
Johannesburg mayor, Herman Mashaba, has met with US officials to discuss the report, according to the newspaper.
