A Michigan man claims he tipped federal investigators to the location of Osama bin Laden's compound in Pakistan years before his killing and is seeking the $25 million reward. A letter obtained by the AP from a law firm representing Grand Rapids resident Tom Lee says the 63-year-old gem merchant reported the location of bin Laden's compound in Abbottabad in 2003. The letter sent by the Loevy & Loevy law firm to FBI Director James Comey in August says a Pakistani intelligence agent told Lee that he escorted bin Laden and his family from Peshawar to Abbottabad. The FBI didn't immediately comment. (More Osama bin Laden stories.)
