Rob Lowe's most recent on-screen government official was Chris Traeger on Parks And Recreationbut for fans of the West Wing, he will always be White House speechwriter Sam Seaborn—a character Lowe cited when taking to Twitter to criticize Sen. Bernie Sanders' rhetoric. Lowe's time as the wordsmith for Martin Sheen's Democratic President from New Hampshire, Jeb Bartlett, was easily the most significant role Lowe has had in Democratic politics since that time in 1988 when he made a sex tape of a threesome he had with a 16-year-old girl on the night of the Democratic National Convention in Atlanta while he was campaigning for Michael Dukakis in real life.
