This is coming amid allegations of drug trafficking.
On Wednesday, he revealed this while appearing on Channels Television’s Politics Today.
A court document allegedly charging Tinubu with drug trafficking and money laundering recently surfaced online.
The document released by the US District Court for the Northern District of Illinois said Tinubu was investigated for money laundering and drug trafficking 30 years ago.
Speaking on the issue, Keyamo said the APC presidential candidate was responsible for the accounts, but some were traced to his mother and “relatives.”
He said: “The US government said he had not paid tax on those interests. That is all and guess what? The banks are supposed to deduct the tax from source.
“Out of the 10 accounts, it was only one account – the one in Heritage Bank – that they took $460,000 as tax on interest that he benefited from the investment he made in those accounts.
“In fact, all the money in Heritage Bank was not taken; they took only $460,000 as tax.”
Keyamo still speaking on the program claimed that the Peoples Democratic Party (PDP) was behind the circulation of court documents linking its presidential candidate, Bola Tinubu, to drug trafficking and money laundering in the United States.
.He said the PDP is scared of the rising profile of Tinubu ahead of the 2023 elections.
Keyamo insisted that there was no criminal indictment or conviction against Tinubu, alleging that the PDP went to the US to dig up the documents and pretended that they went for high-level engagement.
He said: “His (Tinubu’s) detractors kept bringing up these issues over and over when his political profile is rising when he wants to run for office or any political turn in his life, they will bring up these issues.
“The date on the papers flying up and down, the date of certification is 2022, so they are using this to confuse people that these are fresh papers. If documents are 40 years old or 100 years old, once you go to court, and apply for certified true copies of those documents, they will give you those documents but they will stamp the day they are giving you those documents.
“This is what our detractors, the PDP, perhaps that is what they went to the US for when they pretended that they went for high-level engagement. This is part of the high-level engagement they went for.”
