Much of the legal world’s attention was focused this week on Donald Trump’s attacks on Gonzalo Curiel, the federal judge presiding over the Trump University fraud cases in California. The outrage centered on Trump’s insistence that the fact of Curiel’s Mexican ancestry should disqualify him from the case, considering Trump’s declared intent to build a border wall. We discuss Trump’s stance – and its historical antecedents – with Deborah Rhode, founding director of Stanford University’s Center on Ethics. And we sit down with Jeffrey Rosen to talk about the far-reaching legal mind of Justice Louis Brandeis, confirmed to the Supreme Court 100 years ago this month. Rosen is the author of the new book Louis D. Brandeis: An American Prophet.  Transcripts of Amicus are available to Slate Plus members.
