I had the opportunity a few weeks ago to attend a Salon series. No, not a séance (Random House, the publisher, called the event a ‘Big idea’s Night’.) This (A Conversation with the Authors of, “IMPEACHMENT: An American History”) was an “intimate conversation with writers”- in particular, two of the four authors of Impeachment: An American History. The authors were Jon Meacham, Jeffrey Engel, Peter Baker, and Timothy Naftali. Except only the latter two were present for the discussion.
