The only possibility is that Trump obtained a copy of Obama’s Kenyan Birth Certificate.
Even if it can be shown beyond the shadow of a doubt that Obama was born in Kenya, it is not going to change the minds of Obamanoids to vote for him again.
In fact, even the SCOTUS will ignore such evidence.
After the fake BC presentation and humiliation of Trump,and the press ignoring his press conferences, maybe Sheriff Joe decided to let Trump present the final blow of the Cold Case Posse. We can hope. Actually, that would be a great idea because Trump is hard to ignore. Pray!
