A US lobbying firm hired by the Indian government has disclosed in filings under the Foreign Agents Registration Act (FARA) that it arranged US President Donald Trump’s June social media post congratulating Prime Minister Narendra Modi on becoming India’s longest-serving prime minister.

The firm, Mercury Public Affairs, was retained on a monthly fee of $75,000 after Trump’s re-election. It is led by individuals considered part of Trump’s inner circle, including Bryan Lanza, communications director of Trump’s transition team. Susie Wiles, Trump’s outgoing chief of staff, was also a registered lobbyist with Mercury until late 2024, The Indian Express reported on Saturday, citing documents filed by the firm.

Among the activities listed in its filings, Mercury included Trump’s post on X in June congratulating Modi on reaching the milestone.

Another lobbying firm, SHW Partners LLC, headed by Trump aide Jason Miller, disclosed that it had arranged eight phone calls between Indian government representatives and senior White House officials in May and June. Its latest FARA filing described the calls as part of its “political activities” and said they focused on “India-US relations”, according to the report.

India hired Miller’s firm in April 2025, and the contract was extended for another year in April this year. The agreement was terminated on June 23 after Miller joined the Trump administration as a “special government employee”. The Indian Embassy in Washington had signed the contract with SHW Partners for a monthly payment of $150,000.

The contract covered “strategic counsel, tactical planning and government relations assistance on policy matters before the US government, the US Congress, state governments, academic institutions, think tanks, and other relevant stakeholders”.

Under FARA, agents representing foreign principals in political activities must periodically disclose their relationship with their clients, the work they perform and the compensation they receive.

According to the filing, Miller’s firm arranged calls in May, ahead of US Secretary of State Marco Rubio’s visit to India, between Indian representatives and White House officials, including Treasury Secretary Scott Bessent, Deputy National Security Adviser Michael Needham and Under Secretary for Terrorism and Financial Intelligence Gene Lange.

Following Rubio’s visit, further calls were arranged in June with US Trade Representative Jamieson Greer, Trump’s assistant for policy Walker Barrett and Steven Cheung, director of the White House Office of Communications.
