The US Department of Justice is investigating how Iran's supreme leader Mujtaba
built a large global investment portfolio and whether it is linked to Wall
Street banks, in a broad money‑laundering and corruption probe. Investigators
have begun reviewing whether US financial institutions, including JP Morgan and
Citigroup, aided large transfers among companies controlled by Mujtaba and are
examining the role of US correspondent/agent banks. DOJ is mapping the network
to identify potential gaps in banks' due diligence. Banks in Europe and the
Middle East are also under scrutiny. The probe includes property‑related
payments from the network to international brands, including Hilton Global
Holdings.
