A new report says liberal Supreme Court Justice Sonya Sotomayor has been using her staff to pressure libraries to buy her books. An associated Press study has revealed the justice’s  staff has often prodded public institutions that have hosted Sotomayor to buy her memoir or children’s books, works that have earned her at least $3.7 million since she joined the court in 2009. That is conduct prohibited for members of Congress and the executive branch. They’re barred under ethics rules from using government resources, including staff, for personal financial gain.
