On a point of order, I'd like to table a motion on this issue.
The motion would be that witnesses' times not exceed 40 minutes. So you have 10 minutes for the presentation, and then after that we have 30 minutes for questions from members of the committee. Questions can be anywhere from five to seven minutes, alternating from opposition to governing parties for that timeframe. Forty minutes seems to be a fair allotment of time, especially with the number of witnesses we want to see.
So I move that at the end of speaking times--I have this in writing, if you'd like it--we add that testimony of each witness or group of witnesses be limited to 40 minutes unless there is unanimous consent to extend that time.
