“There is no reason for Rove to make this appearance unless he and his counsel believe he is at serious risk of indictment. None.” On the day after former White House procurement chief David Safavian is indicted on five counts of lying and obstruction of justice, Karl Rove decides to testify for a fourth time before the grand jury delving into the felonious unmasking of Valerie Plame (presumably to stave off his indictment, or that of someone above him.) So…Rove, Safavian, Libby, Abramoff, Frist, DeLay…how many investigations and indictments can the GOP leadership rack up? Is the whole rotten edifice of GOP corporate cronyism threatening to topple? One can only hope.
