All week, Washington, D.C., has been talking about Donald Trump’s dinner with Nick Fuentes, a notorious white supremacist and Holocaust denier. A wave of prominent Republicans have repudiated the dinner and anti-Semitism, including Senators Mitch McConnell and Mitt Romney. Trump’s former Vice-President, Mike Pence, condemned the meeting as well, with the caveat that he didn’t think his former boss was a bigot or an anti-Semite. But the issue goes beyond a single meal. The staff writers Susan B. Glasser, Jane Mayer, and Evan Osnos gather for their weekly conversation, to look at the modern history of the far right in Republican politics.
