The unexpected removal of Robert E. Primus by President Donald Trump from the Surface Transportation Board has created new uncertainty around one of the largest corporate deals in the U.S. The $85 billion merger between Union Pacific and Norfolk Southern is already facing significant scrutiny from regulators, shippers, and policymakers. Removing a board member known for raising concerns about unchecked consolidation in the freight industry adds both legal and political complications during a critical time for American rail transport.
Robert Primus, a Democrat appointed to the board by Donald Trump in 2020, reportedly learned about his termination through a brief email sent late on Wednesday evening. The message, issued from the White House Presidential Personnel Office, stated that his position was terminated “effective immediately.” No reasoning was provided in the correspondence, though later a White House spokesperson claimed that Primus did not fit the administration’s “America First agenda.” By the following morning, his name and biography had already been removed from the board’s official website.
The abrupt dismissal has been described by Primus as both “deeply troubling and legally invalid.” In his own words, he insisted that he remains a member of the board until due legal cause is established for his removal. He added that he would continue to carry out his duties and, if obstructed, would resort to legal action. His stance reflects a broader concern about the independence of regulatory bodies in the United States. For decades, boards such as the Surface Transportation Board, the Federal Trade Commission, and the Equal Employment Opportunity Commission were expected to function with a degree of autonomy, even when their members had been appointed by different administrations. Trump, however, has a record of dismissing officials from these agencies, which has drawn criticism from both opposition politicians and unions representing transport workers.
The controversy carries particular weight because of the Union Pacific–Norfolk Southern merger. The agreement announced in July aims to create the first coast-to-coast freight rail network in the country. The combined entity would control around 50,000 miles of track across 43 states and would directly challenge the trucking sector for long-distance freight. Proponents of the deal argue that such scale is required to compete effectively and strengthen the supply chain. Critics, however, including many shippers and independent freight companies, fear that greater concentration will reduce competition, raise costs, and marginalise smaller players.
Primus is not new to dissent on mergers of this magnitude. In 2023, he was the sole board member who opposed the Canadian Pacific–Kansas City Southern merger, another large consolidation in the industry. At the time, he argued that the transaction was not in the wider public interest and could harm competition in the long run. His scepticism towards consolidation has been widely cited as a reason why his removal at this delicate stage may have political undertones.
The financial markets have been watching the developments closely. Norfolk Southern’s shares closed at $272.35 on Wednesday, well below Union Pacific’s $320 per share offer, reflecting investor uncertainty over regulatory approval. Retail traders on platforms such as Stocktwits showed a bearish mood towards Union Pacific and a more neutral stance towards Norfolk Southern, again suggesting caution about whether the merger will be cleared. Union Pacific stock has already fallen by nearly 4 percent this year, while Norfolk Southern has gained close to 15 percent, underlining the uneven market reaction.
Labour unions have strongly criticised the firing. The AFL–CIO’s Transportation Trades Department released a statement warning that replacing Primus with a member who is more sympathetic to large carriers could tilt the board’s balance and weaken its impartiality. The union argued that Primus had consistently acted with fairness and that his removal undermines the credibility of an agency tasked with ensuring a competitive and sustainable freight network.
The timing also coincides with Trump’s wider reshuffling of independent agencies. Only days before, he attempted to dismiss Federal Reserve governor Lisa Cook, who has since filed a lawsuit against the White House, arguing that her removal was unlawful. Similar moves targeting Democratic appointees at other commissions have raised alarm about executive overreach and the politicisation of regulatory oversight. The independence of such boards has been seen as essential to ensuring that corporate mergers, labour practices, and financial regulations are judged on technical and public interest grounds rather than partisan calculations.
Primus himself has had a long career in policy and transportation. Before his appointment to the Surface Transportation Board, he served as an adviser and chief of staff to Democratic representatives in Congress and had earlier worked in the lobbying sector on transportation and national security matters. In 2024, President Biden appointed him as the chair of the board, making him the first Black chairman in its history. After Trump’s return to office, Republican Patrick Fuchs was named chair, but Primus continued as a board member. His removal now eliminates one of the board’s few dissenting voices on consolidation.
In his comments following the dismissal, Primus questioned whether his opposition to consolidation was the true cause. He openly speculated whether his removal was related to his stance on rail mergers or whether it reflected deeper political motives. He also raised the issue of racial bias, noting that he had been the first Black chairman of the board. Such remarks, though cautious, underline how the firing could carry wider social and political implications beyond the merger case itself.
The Surface Transportation Board’s decision on the Union Pacific–Norfolk Southern merger will shape the future of American freight. Supporters of the deal argue that a coast-to-coast rail network will increase efficiency, reduce bottlenecks, and provide a credible alternative to the trucking sector, which has faced labour shortages and rising costs. Opponents warn that concentration of market power in fewer hands risks reducing service quality, weakening bargaining power for shippers, and creating vulnerabilities in the supply chain. The removal of a member known for raising critical questions only deepens the sense of unease surrounding the process.
The broader concern is whether regulatory bodies can maintain their independence in the face of political intervention. If appointments and removals are determined solely by partisan considerations, then the balance of oversight risks being tilted towards whichever administration is in power. This undermines confidence not only in the Surface Transportation Board but also in the wider network of agencies responsible for maintaining checks on corporate power and safeguarding public interest.
