The chronicles of "Doonesbury" creator Garry Trudeau

"Sunday Morning" host Jane Pauley interviews her husband, the Pulitzer Prize-winning cartoonist Garry Trudeau, whose comic strip he started at Yale University in the 1960s, "Bull Tales," evolved into one of the most influential and enduring chronicles of the counterculture. Now 70, Trudeau talks about his Pulitzer Prize-winning strip, and the effect his memorable characters' journey has had on him and his "accidental career." (Originally broadcast on December 2, 2018.)
