And the former top aide to chief White House strategist Karl Rove has stepped down as U.S. attorney for Arkansas. Tom Griffin’s resignation came just hours after Congressmember John Conyers had asked for information about Griffin’s role in a scandal first reported by the journalist Greg Palast for both the BBC and Democracy Now! Palast obtained internal Republican emails showing Griffin had 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.
