Dems "Hijack" the Senate

Eariler today, Harry Reid invoked Rule 21 and made the Senate doors closed for a meeting. Here is there article. It is supposedly in regard to pre-war intelligence in light of the Libby indictment. I have not had a chance to look into the issue very far so perhaps I am way off base here, but I do have one question: Was this an action used by the dems to begin the planning for the confirmation battle?
I am sure they discussed pre-war intel as well (they probably all said how it was all lies), but then I suspect they also used the time to plan for the impending battle that is Sam Alito's appointment.
Just a thought, let me know what you all think.
