President Trump’s personal attorney Rudy Giuliani spoke on the sidelines of the Warsaw summit, calling for the overthrow of Iran’s government during a speech at a rally of Iranian exiles known as the MEK, which was formerly on the U.S. terrorist watch list. Giuliani later admitted he was paid by the group to speak at their rally. This week marks the 40th anniversary of Iran’s revolution, which toppled the U.S.-backed dictatorship.
