A United States-based policy and government affairs firm, Von Batten-Montague York, says it has briefed senior members of President Donald Trump’s team on allegations made by Adeniyi Adeyemi Matthew, the man who claimed to be the Director-General of the controversial Presidential Foreign Intervention Promotion Council (PFIPC), whose appointment and agency were previously disowned by the Nigerian Presidency amid controversy over alleged budget insertions.

The firm disclosed that it would this week begin briefing members of the U.S. Congress over the allegations, which it said involve the alleged misappropriation of World Bank-supported funds by senior Nigerian government officials.

In a statement posted on X on Tuesday, Dr. Von Batten of the U.S. policy firm said he had spoken directly with Adeyemi and found his allegations credible enough to warrant investigations by Congress, the U.S. Department of State, the U.S. Treasury Department, the U.S. Government Accountability Office (GAO), and other relevant U.S. agencies.

“This is Dr. Von Batten. I just spoke with Mr. Adeyemi. I found him to be sincere and credible. Based on our discussion, I believe his allegations warrant an investigation by Congress, State Department, US Treasury, the US Government Accountability Office , and other relevant U.S. agencies due to the alleged misappropriation of U.S.-funded World Bank loans by senior members of the Nigerian government.”

The firm added that the allegations had already been brought before influential members of President Donald Trump’s political team.

“This past weekend, I briefed senior members of President Donald Trump team on these allegations, and our team will begin briefing Members of Congress this week.”

Adeyemi has remained at the centre of public controversy since he surfaced as the purported Director-General of the Presidential Foreign Intervention Promotion Council, an entity the Presidency subsequently described as non-existent and unauthorised. The controversy deepened after reports linked the council to disputed budget allocations and alleged insertions in the national budget.

According to the latest statement issued by the U.S. firm, Adeyemi maintained that he was officially appointed by President Bola Tinubu’s Chief of Staff, Femi Gbajabiamila, to head a Nigerian presidential agency.

The statement said Adeyemi alleged that he was allocated office space within government premises, that bank accounts for the agency were opened through the Central Bank of Nigeria, and that the agency received funding through Nigeria’s national budget, including financing supported by the World Bank Group.

The firm further quoted Adeyemi as alleging that Gbajabiamila demanded a share of the agency’s allocation.

“Mr. Adeyemi further alleges that Mr. #Gbajabiamila demanded 45% of the agency’s budget and that, after he refused, he became the target of retaliation and the agency was subsequently labeled fraudulent or ‘fake.'”

Dr. Von Batten also expressed concern about Adeyemi’s safety, stating that he claimed to be in hiding after receiving threats.

“Mr. Adeyemi informed me that he and his family have received threats and that he is currently in hiding out of concern for their safety.”

The firm warned President Tinubu that any harm to Adeyemi or his family while he is cooperating with U.S. authorities would attract consequences.

“To President #Tinubu, if any harm comes to Mr. Adeyemi or his family while he is prepared to speak with U.S. officials, you will be held responsible and face U.S. justice.”

The latest statement follows an earlier declaration by the firm expressing interest in contacting Adeyemi and offering support if he chooses to seek protection in the United States.

The earlier statement read: “To anyone in contact with Mr. #Adeyemi, we are very interested in speaking with him. We are prepared to assist Mr. Adeyemi in seeking asylum in the United States and requesting whistleblower protection.”

The firm argued that because World Bank Group funds reportedly constitute part of Nigeria’s national budget, and with the United States being the institution’s largest shareholder, any credible allegations involving those funds would be of significant interest to U.S. authorities.

It added: “Because World Bank Group funds reportedly form part of #Nigeria’s national budget, and the United States is the World Bank’s largest shareholder, any credible allegations involving those funds would be of significant interest to U.S. authorities.”

The firm also warned the Nigerian government against any action that could endanger Adeyemi.

“To the government of President Bola Tinubu and his Chief of Staff, Femi Gbajabiamila: if any harm comes to Mr. Adeyemi, we will call for a full investigation and for those responsible to be held accountable.”

Earlier, SaharaReporters reported that Prince Adeniyi Adeyemi Matthew, who has been accused of posing as the Director-General of the Project Fund and Public Infrastructure and Finance Commission (PFIPC), wrote an open letter to President Bola Ahmed Tinubu, calling for an independent, multi-stakeholder investigation into the alleged PFIPC scandal and the controversial ₦1.3 billion allocation inserted into the 2026 Appropriation Bill.

In the letter dated July 13, 2026, Adeniyi commended President Tinubu’s directive to the Independent Corrupt Practices and Other Related Offences Commission (ICPC) to investigate the circumstances surrounding the alleged scandal but argued that the probe should be broadened to guarantee transparency and public confidence.

Addressing the President, he wrote: “I write to you not as a fugitive evading accountability, but as a Nigerian citizen who maintains an unwavering belief in equity, justice, and the rule of law.”

He added: “I commend your recent directive tasking the Independent Corrupt Practices and Other Related Offences Commission (ICPC) with investigating the circumstances surrounding the PFIPC Scandal and ₦1.3 billion allocation inserted into the 2026 Appropriation Bill.”

According to him, “This directive is a vital first step, but the structural realities of this investigation compel me to speak out of a profound desire for absolute transparency.”

Adeniyi argued that an impartial investigation would be difficult under the current arrangement, stating that “obtaining a truly impartial hearing presents severe structural challenges.”
