New Delhi: A US lobbying firm that worked for the Union government has disclosed in its filings under the US’s Foreign Agents Registration Act (FARA) that it organised US President Donald Trump’s social media post on Truth Social in June on Prime Minister Narendra Modi becoming India’s longest-serving prime minister.The firm in question, Mercury Public Affairs, led by people seen as a part of Trump’s inner circle was signed on a monthly retainer of $75,000 after his re-election. Bryan Lanza, communications director of Trump’s transition team, is part of its core team. Susie Wiles, Trump’s outgoing chief of staff, was also a registered lobbyist with Mercury until late 2024, The Indian Express’s Divya A. reported.Among other items in its filings, Mercury has listed a post on X in which Trump congratulated Modi in June on becoming India’s longest-serving prime minister, as per the report.Another firm, SHW Partners LLC, headed by Jason Miller, Trump’s aide mentioned eight phone calls that it set up between the Union government and senior White House officials in May and June. Its latest filing under the FARA describes the calls as part of its “political activities” and says they were held to discuss “India-US relations,” the report added.India hired Miller’s firm in April 2025, and the contract was extended for a year this April. It 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 LLC for a monthly payment of $150,000.As per the documents, the work 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.”FARA obliges “agents of foreign principals” who carry out political activities to periodically disclose their relationship with the client, their work and their financial compensation.According to the filing, calls were arranged by Miller’s firm in May, before US Secretary of State Marco Rubio’s India visit, between the Indian side and White House officials including treasury secretary Scott Bessent, deputy NSA Michael Needham and under secretary for Terrorism and Financial Intelligence Gene Lange.After Rubio’s visit, in June, the Indian side spoke to US Trade representative Jamieson Greer, assistant to Trump for policy Walker Barrett, and Steven Cheung, director of the White House Office of Communications.
