U.S. lobbying firm Valcour, hired by the Serbian government, helped arrange an interview with then-Serbian President Aleksandar Vučić for conservative outlet Breitbart and later drew U.S. President Donald Trump’s attention to the interview, according to records filed by the firm with the U.S. Department of Justice, as reported by N1.
The filing shows that Valcour representatives sent Trump a message on the same day the Breitbart interview was published in May, specifically directing his attention to the interview. Trump subsequently shared a link to the interview on his Truth Social account without adding a comment.
Valcour was hired by the Serbian government in November 2024 for a monthly fee of $65,000. According to the latest filing, covering the period from March through September 2026, the firm received $794,084.79 from Serbia, including its regular monthly compensation and additional legal expenses.
In the Breitbart interview, conducted by the outlet’s Washington bureau chief Matthew Boyle, Vučić praised Trump, saying the U.S. president was more popular in Serbia than any other American leader because he was “pragmatic and rational.”
The Valcour filing shows that the firm’s representatives were in contact with Boyle several times between April 1 and May 31, when the interview was published. On the publication date, the filing separately records a message to Trump drawing his attention to the Breitbart interview. Trump shared the link on Truth Social after 2 p.m. Eastern Time.
At the time, then-acting Serbian President Ana Brnabić said that both Trump and Chinese President Xi Jinping, whom Vučić met during the same period, had shown “great respect” for Vučić and placed Serbia in a position it had not occupied “even during Tito’s time.”
Valcour’s Work Extends Beyond EXPO 2027
Valcour describes its work for Serbia as providing strategic communications, public relations and other consulting services connected to promoting Serbia as the host of EXPO 2027.
However, N1 reported that the current and previous filings reviewed by the outlet do not indicate that the firm’s activities are focused exclusively on the exhibition and instead show a broader range of political and diplomatic engagement.
The latest filing shows Valcour representatives contacted officials at the U.S. State Department and Congress regarding bilateral relations between Serbia and the United States. The firm also relayed what the filing describes as Vučić’s condemnations of antisemitism, although it does not specify which incident or incidents those statements referred to.
Valcour also contacted media outlets, proposing stories and interviews related to U.S.-Serbia relations.
For the March-September period, Serbia paid Valcour $794,084.79, according to the filing.
An earlier report covering September 2025 through March 2026 said Valcour had worked on arranging meetings between Serbian Foreign Minister Marko Đurić and prominent Jewish organizations in Washington. It also reported contacts with State Department officials and Richard Grenell, the former U.S. envoy for Serbia and Kosovo who now serves as an envoy for special missions.
Valcour Director Has Trump Administration Background
The contract with Serbia was signed by Valcour director Matthew Mouers, who previously worked in the Trump administration.
According to his biography cited by N1, Mouers served as a senior White House adviser at the State Department and had previously played a prominent role in Trump’s campaign. He also worked on Trump’s transition team ahead of his second term and was involved in fundraising for the Trump-Vance inauguration committee. He remains involved with the Republican National Committee, according to the report.
Valcour is one of several lobbying firms working in Washington on behalf of Serbia as Belgrade seeks to maintain and strengthen its political and diplomatic ties with the United States.
