Hillary Clinton has spent more than half of her life in the public life - as first lady of Arkansas and the United States, as a U.S. Senator from New York, and then as Secretary of State. As she prepares to accept the Democratic nomination for president, NewsHour's Hari Sreenivasan sits down with two journalists who have penned biographies of Mrs. Clinton: Mark Lander, author of "Alter Egos: Hillary Clinton, Barack Obama and the Twilight Struggle Over American Power," and Michael Tomasky, author of "Hillary's Turn: Inside Her Improbable, Victorious Senate Campaign."
