Lawrence O'Donnell, who's displayed a penchant for PlameGate progression prognostication

And, according to O'Donnell, it's the reason why Rove is voluntarily headed back for 11th hour grand jury testimony.

So, Luskin is sending Rove back into the grand jury to try to get around the prosecutor and sell his innocence directly to the grand jurors. Legal defense work doesn't get more desperate than this. The prosecutor is happy to let Rove go under oath again--without his lawyer in the room--and try to wiggle out of the case. The prosecutor has every right to expect that Rove's final under-oath grilling will either add a count or two to the indictment or force Rove to flip and testify against someone else.

According to some legal experts, it's a risky move for Rove. Murray Waas believes the 4th Rove grand jury appearance will be centered on his slippery words and conflicting statements.

Rove will appear voluntarily, but during tomorrow's session, Rove will be pressed about issues as to why his accounts to the FBI and grand jury have changed, or evolved, over time. He will also be questioned regarding contacts with other senior administration officials, such as then-deputy National Security advisor Stephen J. Hadley and I. Lewis Libby, the chief of staff to Vice President Dick Cheney in the critical week before the publication of columnist Robert Novak's column on July 14, 2003, which outed Plame as a covert CIA operative.

Rove is also likely to be asked more detailed questions about his conversation with Time magazine Matthew Cooper on July 11, 2003, in which Cooper himself has testified to the grand jury that Rove had told him that Valerie Plame was employed by the CIA, and had played a role in having her husband, ambassador Joseph C. Wilson IV, selected to go on his controversial fact-finding mission on behalf of the CIA. Rove's previous grand jury appearances had occurred prior to Cooper's own testimony to the grand jury.
