Donald duke oyinlola present obasanjos coalition group launch

I think there may be a slight mistake in your question. Donald Duke is a former Governor of Cross River State in Nigeria, not Oyinlola. Also, Obasanjo is a former President of Nigeria, not a current one.

However, I'll try to provide some information based on my knowledge.

In 2019, former President Olusegun Obasanjo launched a coalition group called the African Democratic Congress (ADC) to challenge the ruling All Progressives Congress (APC) and the opposition Peoples Democratic Party (PDP) in the 2019 Nigerian general elections.

The launch of the ADC was attended by several notable Nigerians, including Donald Duke, who was one of the founding members of the party. Other notable attendees included former Governor of Osun State, Olagunsoye Oyinlola, who was also a founding member of the party.

The ADC was formed with the aim of providing an alternative to the dominant APC and PDP, and to promote good governance, transparency, and accountability in Nigeria. However, the party did not make significant impact in the 2019 elections.

Please note that this information is based on my knowledge cutoff in 2021, and there may be more recent updates on the ADC or other political developments in Nigeria.
