What does our system say, and do, about impeachment? Professor Cass Sunstein will offer a nonpartisan, historical guide, with some reverence, and even awe, for our constitutional order, and for the power it gives to We the People. By far the most cited law professor in the United States, Cass served as administrator of the White House Office of Information and Regulatory Affairs under Obama, has been involved in constitution-making and law-reform activities in a number of nations, and is renowned for his books, including Nudge: Improving Decisions About Health, Wealth, and Happiness; and Wiser: Getting Beyond Groupthink to Make Groups Smarter.
