Libby Was Judith Miller’s Source

Now that this has been revealed (has it been “leaked”?) will Miller be kept in jail only by Libby’s refusal to come clean? He always could have, and still can, come forward unilaterally and say “I was her source” and get her out of jail. Bush publicly ordered ALL of his staff to cooperate with the prosecutor completely in this case. Do his orders not apply to Dick Cheney’s staff? WHO IS THE PRESIDENT OF THE UNITED STATES?
