Sure, OK, he’s an US Citizen, “now”.
He’s just not an US Natural Born Citizen, nor will he ever be.
He is not Canadian. You said he was. You either lied, or are just ignorant.
And courts have affirmed his being a US Natural Born Citizen. You can choose to remain ignorant about that fact as well if you’d like.
Embrace ignorance, EG. Reject evidence, facts, proof.
