What was the Iran deal that Trump ripped up?

Available for over a year

When President Trump talks about his attempts to reach an agreement with Iran, he often mentions a previous deal: the 2015 JCPOA. Trump pulled America out of the Obama-era accord during his first term and has called it, "the worst deal in history". His own deal, he says, "will be FAR BETTER". Asma speaks to Ambassador Wendy Sherman, the lead US negotiator on the JCPOA, to get the inside story on how the deal was done, and ask what it might take for Trump to get a deal now.
