Author Joan Brady talks with host Matthew Stevenson about the Alger Hiss case, which gripped the United States from 1948 until 1950, when the former State Department official was convicted—Brady says unjustly—of perjury for denying he knew a purported Communist named Whittaker Chambers.  According to Brady's new book, in helping to convict Hiss, Richard Nixon, who later was elected U.S. President, worked to fabricate evidence against Hiss.
