But Trump’s Presidency has enabled a comeback. In recent years, as Dershowitz approached the age of eighty, his public presence faded a bit. With help from research assistants, he has published three dozen books-including “ The Best Defense,” “ Chutzpah,” and “ Sexual McCarthyism”-that recount his cases and advance his opinions. Over the years, he has written thousands of newspaper articles, magazine columns, and Web posts. Intellectually nimble and supremely confident, he is an emeritus professor at Harvard Law School but also an occasional reader (and subject) of the tabloids. If you are a television producer putting together a segment about a celebrated criminal case, Dershowitz is an ideal booking. Dershowitz is a frequent guest on shows like “The View” for decades, he has been a frequent guest just about everywhere.
