In an effort to get his third term bid sail through, former President Obasanjo was alleged to have bribed each member of the then National Assembly who signed to support  amendment of the Constitution with the whopping sum of #50 million.
The Senator representing Nasarawa West Senatorial Zone in the Senate, Abdullahi Adamu disclosed this at a press briefing in Abuja as a reply to Obasanjo for accusing President Buhari led Federal Government of being selective in its anti-corruption war.
" Obasanjo knows as well as I and other leading members of the PDP (then) that he badly wanted it (the third tenure ) and initiated the process of constitutional amendment. He bribed each member of the National Assembly who signed to support the amendment with the whopping sum of #50 million.
"The fresh mint money was taken in its original boxes presumably from the vaults of the CBN, and distributed among the legislators. The money was not his, and it was not appropriated by the National Assembly as required by law.
" Chief Obasanjo said that President Buhari is selective in his anti-corruption war, I agree with him because if President Buhari were not selective, Chief Obasanjo himself would be in the dock today on a trial on charges of corruption arising from the corrupt practices in the pursuit of his third term gambit in the National Assembly in 2006. I therefore, agree that in failing to make former President Obasanjo account for the money, Buhari is waging his anti-corruption war selectively."
Sen. Adamu who is the chairman of the Northern Senators Group stated that President Buhari was not bothered to interrogate Obasanjo's role in the Halliburton scandal for which Americans involved were jailed. The former Governor of Nasarawa State also disclosed that if President Buhari would look into the affairs of Siemens in which the former  President's administration was indicted, he (Obasanjo) would have been in prison."
He therefore concluded that had it been that anti-corruption war of PMB were to be total and blanket in nature, corrupt-minded Nigerians like Obasanjo ought to be in jail by now. To him, Obasanjo lacked moral standing to counsel Buhari against seeking a constitutional second term in office while he sought for a third tenure which did not exist in the Constitution.
