The oval office format will be a challenge for Trump.
He'll be reading from the prompter, a speech written by Stephen Miller ( the dark side of the moon guy)
He won't have a crowd to feed off of.
and with luck networks will have a scroll pointing out the facts vs lies.
and the dem's will have a follow up to make the contrast based on facts.
I think if he claims an emergency, that might be his only exit. This way it will be stuck in court, he can open the government, and claim he's at the mercy of the justice system.
