There are some options here.
I think we're all in agreement with having government officials and the ambassador on Tuesday. That's pretty straightforward. That should go forward. The subcommittee can meet this week, or Wednesday, or Monday next week. We can still be in a position to have witnesses in place for Thursday. I strongly encourage to do everything you can to have your subcommittee this week, and find a slot to have that and make that happen.
You pretty well have consent from all parties to have government officials and the ambassador here on Tuesday. Let's aim for that.
If we're looking at Line 5, if that's what has to be done by April 15, we could actually start submitting witnesses for that for Thursday. The subcommittee can still do its planning. The clerks can have a list of witnesses to contact, and start slotting in witnesses in those time slots. If you said Tuesday and Thursday are our time slots, the clerks know that and they can start coordinating witnesses for those Tuesday and Thursday time slots.
