An official in U.S. President Donald Trump’s Cabinet and at least one of his advisers gave paid speeches to organizations linked to an Iranian exile group that killed Americans before the 1979 Islamic Revolution, ran donation scams and saw its members set themselves on fire over the arrest of their leader. Elaine Chao, confirmed this week as Trump’s transportation secretary, received $50,000 in 2015 for a five-minute speech to the political wing of the Mujahedeen-e-Khalq, previously called a “cult-like” terrorist group by the State Department.
