CHAPPAQUA - Hillary Clinton signed copies of her new book, "Hard Choices," at the Chappaqua Library today.

Security was extra tight at the library, following the recent vandalism of a sign promoting the event.

While Clinton protesters made their voices heard across the street, fans inside the library said they were excited to meet her.

Some Clinton supporters came to the event from out-of-state, and one Clinton fan flew in from Mexico to see her.

Book sales have been sluggish, and Clinton is hoping for a rebound.
