John Hudak, deputy director of the Center for Effective Public Management and senior fellow in Governance Studies, discusses why marijuana is an important public policy issue and how its image is changing, which is the focus of his new book, "Marijuana: A Short History."

Also in this episode, David Wessel, senior fellow in Economic Studies and director of the Hutchins Center on Fiscal and Monetary Policy, provides his regular economic update.

Finally, Fred Dews reviews the highlights of what Brookings experts have said in the previous week regarding the Trump administration in our new "First 100 Days" segment. This week: the "Muslim ban," Trump's trade stance, moving the US embassy in Israel from Tel Aviv to Jerusalem, and the attack on sanctuary cities.
