Harriet Miers---Can she testify on her own?

[Kingofalldems]

She has resigned. I wonder if Bush can legally stop her from testifying.

[Sanity Claws]

1. Executive privilege belongs to the president so only he can

waive it. So what does it mean in procedural terms? If Bush knows she's willing to testify under oath, then he can go to court and try to get an injunction. I think that would be tough, even with the Republican bench.
Regardless of the legal procedures that could be available, my guess is that Bush would prefer to go behind the scenes and threaten her or otherwise force her to change her mind.

On edit:
I forgot that Miers was also his attorney. That means that Bush could invoke attorney-client privilege and demand that she not testify since he has the privilege. She can't waive it for him and she could be subject to disbarment or other discipline if she violated the attorney-client privilege. This threat would be very effective, at least in the interim. There would be a lot of back and forth as to whether her proposed testimony was covered by the privilege.
