Alan Dershowitz: Shunned for defending the 'Constitution on behalf of a president I didn't vote for'

Harvard law professor emeritus Alan Dershowitz discusses the pushback he has recevied from his own party for "sticking to principle refusing to become a partisan,” saying that it has cost him and his family "tremendously,” after he was a member of former President Trump's legal team during his first impeachment trial. Dershowitz also discusses his new book, "The Price of Principle: Why Integrity is Worth the Consequences."
