When you look at the House itself when it's sitting, members have the right to walk out or stay in the room. That is their prerogative. Therefore, for us to determine that they have to be there when the questions are being asked or when proceedings are taking place is something you may want to study as a committee; however, I would recommend that it happens in virtual time just like it does in House time. There is not much difference.
