My complaint:
Absolutely irresponsible and misguided decision. I thought this was a reputable journalistic institution, not a vehicle for a trump campaign ad.
Reschedule it for another time, so principles of journalism can be respected by allowing the viewers to see both candidates. You should be ashamed of yourselves.
Suggested solution:
Rescind this decision and reschedule. Don't think I'll be watching NBC anytime soon.
