A US-based lobbying and advisory firm, Von Batten-Montague-York, has called on the US State Department to publish the signed memorandum of understanding (MOU) between Nigeria and the United States on critical minerals, saying publication would help address allegations surrounding the agreement.
In a post on its verified X account, @batten_von, the firm said the “integrity of the United States is on the line” and claimed that Democrats in the US House of Representatives were signalling plans to investigate the Trump administration’s critical-minerals deals and the officials involved in negotiating them. The firm also referred to allegations of corruption and “pay-to-play” reportedly being raised by Democrats, although it rejected those allegations as “ridiculous.”
The firm’s call comes amid increasing scrutiny from US lawmakers over the Trump administration’s critical minerals agreements. In August 2026, 54 House Democrats, led by Natural Resources Committee Ranking Member Jared Huffman, Ways and Means Trade Subcommittee Ranking Member Linda Sánchez, and Congressman Jonathan Jackson, sent a letter to top administration officials warning that the deals lacked transparency and congressional oversight . The letter specifically raised concerns about potential benefits flowing to administration insiders, including the families of President Trump and Commerce Secretary Howard Lutnick, while leaving American taxpayers exposed to financial losses .
The Democrats pointed to reporting by the New York Times indicating that businesses connected to the Trump and Lutnick families stand to gain from a US-backed minerals arrangement with Kazakhstan . They also warned that the agreements commit US taxpayers to billions of dollars in loans, loan guarantees, and equity stakes arranged through the Development Finance Corporation and the Export-Import Bank, agencies they said were operating with weakened safeguards .
The firm subsequently linked the debate over the US-Nigeria minerals agreement to the deaths of 37 suspected illegal miners in the custody of the Nigeria Security and Civil Defence Corps (NSCDC) in Niger State. The 37 detainees died after being arrested during anti-illegal-mining operations in Niger State on September 15 and 16 . Nigerian authorities have ordered an independent investigation into the deaths, while officers connected to the incident were suspended .
Reuters reported that many of those who died were teenagers and that survivors described severe overcrowding and poor ventilation in the detention facility. The exact cause of death has not been conclusively established .
In its post, Von Batten-Montague-York alleged that Nigerians were questioning whether the deaths were connected to Nigeria’s mineral resources and negotiations with the Trump administration. The firm further alleged that the mines were being described by Nigerian government officials as a settlement or “bribe” to the Trump administration. That allegation has not been independently established and is presented here as a claim made by the firm.
The call comes days after Nigeria and the United States signed a framework agreement aimed at attracting American investment into Nigeria’s mining sector . The agreement was signed in New York by Nigeria’s Minister of Solid Minerals Development, Dele Alake, and US Deputy Secretary of State Christopher Landau .
According to the Nigerian government, the framework covers geological data and exploration, mineral development and processing, infrastructure, and technical capacity building . Nigeria estimates its mineral resources at about $700 billion . Reuters reported that the agreement is part of Washington’s broader effort to strengthen relationships with mineral-producing countries and diversify supply chains for critical minerals .
Alake described the agreement as one that would shape the future of Nigeria’s mining industry, stressing that the country was determined to move beyond the export of raw minerals . “A signature is a promise, results are the proof,” he said .
Von Batten-Montague-York is now urging the US State Department to publish the signed MOU, arguing that making the document public would help dispel what it described as growing accusations of corruption.
The call for transparency echoes concerns raised by Nigerian stakeholders. Former Kaduna Central Senator Shehu Sani faulted the Federal Government over the $700 billion mineral deal, saying the details should have been made public earlier for parliamentary scrutiny . Sani warned that the agreement should not become merely a mechanism for replacing Chinese mining interests or appeasing any foreign power, adding that “a mineral deal is not just an economic issue but also a sovereignty issue that must be treated seriously” .
