From Pay2Play:

Karl Rove was served with a subpoena Sunday, Oct. 24th, 2010, as he arrived at CBS studios to appear on “Face the Nation.” The subpoena was to compel Rove to provide a deposition in a lawsuit that stems from the 2004 election in Ohio. Despite the fact that news crews from CBS and CNN taped Rove being served, neither have reported it or aired the footage.
