Bo Obama, the curly black-and-white first dog, was worth $1,600 when the late Sen. Ted Kennedy gave him to the first family, President Obama’s financial-disclosure forms show. Because the pooch was a gift, the president had to disclose his value. The forms also reveal Obama made several million dollars in book sales, which are invested in U.S. Treasury bills. Vice President Biden also released his financial-disclosure forms, showing him to be far less wealthy and mostly invested in mutual funds. Notable gifts Biden disclosed include a first-edition copy of "Anna Livia Plurabelle," signed by author James Joyce and valued $3,500. The gift came from Margaret Spane, a 97-year-old widow, who saw a speech in which the vice president said Joyce was his favorite poet.
