According to messages reviewed by U.S. authorities, Ambani sought guidance in 2017 on navigating U.S.-India relations and defense cooperation.
Epstein, despite no proven official role, claimed he could provide inside information and advice on dealing with the White House.
The exchanges suggest Epstein shared advance insights on key U.S. appointments and foreign policy decisions.
In one instance, he indicated that David Petraeus was unlikely to be appointed U.S. ambassador to India—an assessment that later proved accurate.
He also predicted that John Bolton would replace H. R. McMaster as national security adviser, which occurred months later.
Epstein further offered to connect Ambani with influential figures close to Donald Trump, including Steve Bannon and Tom Barrack.
While some of Epstein’s information appeared accurate, the report notes there is no evidence he had formal ties to the administration, raising questions about whether his access stemmed from real connections or well-placed sources.
