Welcome to the cbs overnight news. Im tony decople. Donald trump is pointing fingers at Hillary Clinton over a 400 million payment the u. S. Made to iran as the landmark nuclear deal was taking effect. The transfer came in january the same day iran released five jailed americans. The white house insists the payment was part of a case over seized iranian assets. Donald trump calls it ransom, originally cooked up when clinton was secretary of state. Was this money ransom for the folks released . No, it was not. It is against the policy of the United States to pay ransom for hostages. Just a coincidence . Margaret brennan has the story. Reporter the Obama Administration long said a nearly 2 billion settlement with iran was unrelated to the prisoner release though they happened at the same time and also coincided with implementation of the landmark deal to freeze Irans Nuclear program. When iran released four american prisoners in january, including journalist, jason rezain, and a former marine it was heralded as a diplomatic breakthrough. A coalition of congressmen met three of the americans in germany at the Regional Medical center. We paid a price in a major way to bring them home. Reporter the administration strongly denied paying any ransom. But according to new details first reported by the wall street journal, 400 million in cash was flown into tehran on a cargo plane, around the same time that the americans were handed over. It was loaded with euros, swiss franks and currencies since any transaction with iran in dollars is illegal under u. S. Law. Senior u. S. Officials claim the timing was coincidental. And just the first payment of a separate 1. 7 billion settlement. At the time, president obama did not provide detail, but did say the money was meant to settle an outstanding legal dispute from before the 1979 islamic revolution. Nuclear deal done, prisoners released, the time was right to resolve this dispute as well. Reporter the Administration Never consulted Congress According to republican congressman ed royce who accused the white house of paying ransom to a state sponsor of terrorism. As details became public tuesday, there were instant reverberations on the campaign trail. Republican Vice President ial nominee mike pence. The Administration Air lifted 400 million in cash to iran. You know, we cannot have four more years accommodating and apologizing to our enemies or abandoning our friends.

But a recent poll found that 63 of brazilians think hosting the games here is actually doing more harm than good. Rio de janiero. Reporter when rio won the right to host the olympics in 2009, a throng of brazilians were bouncing on the beach. It was their chance to show the world that brazil had arrived. But then, the worst recession in 25 years hit. And unemployment shot up alongside billions of dollars worth of olympic venues. Its beautiful. This is home. Reporter felipe piva lives in one of rios poor neighborhoods known as favelas. All this money spent on olympics is anything Getting Better for you or people that live in the favelas.

Only two cities wanted the 2022 winter olympics. Almaty kazakhstan, and beijing. Both with major human rights issues. Beijing got the games. The International Olympic committee has reformed the bid process encouraging more reuse and renovation of facilities versus insisting on brand new stadiums. Rio is touting socalled legacy projects.
