Did the Veep's office try to sway Judith Miller's testimony:
New details about Judith Miller's decision to cooperate in the CIA leak probe are raising questions about whether Vice President Dick Cheney's chief of staff and his defense lawyer tried to steer the New York Times reporter's testimony.
...In urging her to cooperate with prosecutors, Libby wrote Miller while she was still in jail in September: "I believed a year ago, as now, that testimony by all will benefit all. ... The public report of every other reporter's testimony makes clear that they did not discuss Ms. Plame's name or identity with me."
Here's a better question: why would the Veep's office think they needed to sway Miller's testimony? She's the most reliable tool in the White House's shed.
