Amanda Knox has signed with a literary agent who has brokered book deals for President Barack Obama, Sarah Palin and Hillary Clinton, among others.

TMZ reported Monday that Knox -- who was freed from an Italian prison in October after a court overturned her murder conviction because of unreliable DNA evidence -- will be represented by Washington-based lawyer and literary agent Robert Barnett as she shops a book about her story.

Knox, 24, was convicted in December 2009 of the murder of her British roommate Meredith Kercher in Italy.

She spent four years in an Italian prison before she was acquitted when forensic experts disputed some of the DNA evidence used to convict Knox and co-defendant Raffaele Sollecito, her Italian boyfriend.

Sollecito, who was also cleared of the murder, has signed with literary agent Sharlene Martin for a book of his own, sources told TMZ.
