Unfortunately, given the current context, and since the schedule is set by the whips, I am not sure the committee can extend its regular Wednesday meeting by 30 minutes or one hour.
However, I don't know whether you noticed, but the time slots adopted by the whips now include spots reserved for committees that decide to meet in camera, for instance. We could decide to hold an additional meeting in one of those time slots. There is a time slot available on Tuesday, June 9, from noon to 1 p.m., and another one on June 10, from 11 a.m. to noon. That is a suggestion.
