In a special episode of Squawk Pod, Joe Kernen, Becky Quick, and Andrew Ross Sorkin are at the World Economic Forum in Davos, Switzerland, where they’re speaking with JPMorgan Chase CEO Jamie Dimon. He takes a hard look at American political tribalism in the wake of the Iowa Presidential Caucus, and he considers the trajectory of the U.S. economy. Plus, Dimon says that China is gladly opening up to foreign investments, and he’s done talking about bitcoin–after this! Jamie Dimon talks about pet rocks, blockchain technology, and market hype.  In this episode:Becky Quick, @BeckyQuickJoe Kernen, @JoeSquawkAndrew Ross Sorkin, @andrewrsorkinCameron Costa, @CameronCostaNY
