So Bush has already said dem's should accept his offer for the top white house aides to testify privately, not under oath, with no transcript. The congressional committee said they will pursue subpoenas, and i just heard they approved going ahead with issuing subpoenas today. Showdown is set between Bush and congress. Lets see how the balance of powers prevails. If there was no illegal/unethical conduct involved with the firings why would bush refuse to allow them to testify before congress under oath?
