In the spirit of cooperation, we want to make sure every person also has an opportunity to ask a question before another member of the committee asks multiple questions of the witness.
I've sat on about three different committees. I've experienced the ten-minute first round and the five-minute first round. There are advantages to both, but in each case there were some problems when one member had multiple opportunities to ask questions before others were given a chance. So perhaps we could work into the policy and the procedure that everybody has a chance to ask a question before a member of a party has multiple opportunities.
