It’s been pointed out to me that this article is about a year old, so the registration requirement has likely gone by the wayside. I apologize for the unnecessary pot-stirring.
Looks like Mr. Trump wants to have certain people registered:
I hereby promise and commit that if any group or groups are required to register, I will be among the first to register as a member of that/those group(s).
I’m thinking of getting an armband that supports multiple stigmata.
