Must be for something he hasn’t publicly apologized for in the past. Doesn’t include sarcastic apologies.

Edit: To clarify, public apologies only. Reports of private apologies don’t count unless trump publicly confirms that he made them.

Edit 2: An apology must entail taking responsibility for something he had personal control over.

I’m sorry for the families who died on 9/11 = not an apology

I’m sorry that this arena (picked for a rally) flooded = an apology
