Hillary Clinton Building Case for 2016 Presidential Run

Hillary Rodham Clinton says she hasn't decided if she'll run again for president. But she's giving more reasons to run than not.

Clinton's on a frenetic tour promoting her new book, "Hard Choices." She's been making case after case for launching a new presidential campaign in 2016.

The former secretary of state pushes back against Republicans investigating the deadly raid on the American compound in Benghazi.

Clinton says she wants to keeps faith with the women and girls who look up to her.

And she says she now knows how not to run a campaign, after the bitter experience of losing the Democratic nomination to Barack Obama in 2008.

Her main reason not to run? Clinton says she enjoys her life as a high-dollar speaker, advocate and soon-to-be grandmother.
