Welcome to Debrief, the new podcast hosted by Bloomberg Businessweek Editor Megan Murphy. With each episode, we'll sit down with the world's leading business leaders, entrepreneurs and political figures. It's a peek behind the scenes of global business, culture and politics -- a first-hand conversation with the people who shape the world's economy.

In this episode, we speak with Jamie Dimon, the billionaire CEO of JPMorgan whose storied business career includes stints at Citigroup and American Express. The New York Times once called him "Obama's favorite banker.'' But for now, it looks like he won't be joining the Trump administration. We caught up with Jamie in mid-December in Detroit, where he was speaking at the restored Garden Theater about the bank's $100 million investment in revitalizing the city.
