Halliburton scandal sans questioned efcc
I think there may be a bit of a misunderstanding here!
The Halliburton scandal refers to a series of controversies and allegations of corruption and fraud surrounding the company Halliburton, a multinational energy services corporation, during the 1990s and early 2000s.
The scandal involved allegations of overcharging the US government for services provided in connection with the reconstruction of Iraq after the Gulf War, as well as allegations of bribery and corruption in connection with the company's business dealings in Nigeria and other countries.
The scandal was widely reported in the media and led to numerous investigations and lawsuits, including a major investigation by the US Senate Permanent Subcommittee on Investigations.
As for the EFCC (Economic and Financial Crimes Commission), it is a Nigerian government agency responsible for investigating and prosecuting financial crimes, including corruption and fraud. While the EFCC may have investigated or prosecuted some cases related to Halliburton's activities in Nigeria, I'm not aware of any specific cases or investigations that have been "questioned" by the EFCC.
If you have any specific questions or concerns about the Halliburton scandal or the EFCC's investigations, I'd be happy to try to help clarify things for you!
