Tariffs. Trade wars. Global supply chains. Sound confusing? You’re not alone — and former Cabinet member U.S. Trade Representative Katherine Tai is here to break it all down. In this episode one of President Biden's main trade architects explains:

• Who typically oversees trade for the United States

• What trade policy is

• What tariffs are

• What Trump is doing with both

• What we should be doing instead

• How we move forward as a country -- and as a world

This is the trade episode for people who didn't think they needed it -- but are now learning the hard way that they do.
