>> coming up next on booktv, took notes from january 2000, arthur herman discusses his book, joseph mccarthy. reassesses mr. mccarthy's legacies and supports the senator from wisconsin was justified in arguing that there was a real communist threat inside the u.s. government. this is about an hour. .. and to understand where that came from and maybe to resort every think just what we really do and how we assess joe mccarthy now, with almost 50 years of distance between ourselves and him. c-span: if you were there at his most visible time, where would you find him? >> guest: there at his most visible time? c-span: in history. >> guest: that would be 1950 to 1954. it's a very sharply defined career, meteoric. it starts in february of 1950, when he makes his famous speech at wheeling, west virginia, accusing the state department of harving--harboring communists and communist superfized -- sympathizers. and then it really comes to a crashing conclusion in december of 1954 when the senate censures him, and that really is the end of joe mccarthy as a--as a public figure, although not as a senator.
