This is the full Senate, not just the committee.
I think that Senate rules require a cloture vote (now simple majority) to cut off floor debate. Following the cloture vote, I seem to remember that an additional 24 hours of debate is allowed at which point the confirmation vote (simple majority) can be taken. They can keep the Senate in session through the weekend to meet the procedural issues. In these crazy times, it appears everything is subject to change, however.
