In Washington, U.S. Senators Edward Kennedy of Massachusets and Sheldon Whitehouse of Rhode Island are demanding a probe into allegations Republicans deliberately tried to prevent people of color from voting in the 2004 elections. Internal emails show Republicans including former Karl Rove aide Tom Griffin sent so-called voter “caging-lists” designed to challenge voters from casting ballots. The caging lists were skewed toward targeting people of color, predominantly African Americans. Griffin announced his resignation as U.S. attorney in Arkansas earlier this month.
