They just want to stage it during the day to grab microphone time. Jackasses.
More TV time shouldn’t have been the reason. (although they are terribly inept) They were in prime time in 3/4 of the country, and in the east coast in the 11pm news hour. Couldn’t have been better exposure.
Perhaps they did NOT want all those available eyeballs to see it. Far fewer will witness it Friday. Travel plans would likely be interrupted for all members.
I suspect something else.
