You're making a pretty big leap of assumption here.

- he didn't say that he had biological kids

- the step daughter is his own daughter, they aren't two different things

- he didn't say that if he does have biological kids, that he didn't tear up at their graduation

- he also didn't specify the ages of any of his kids, so there's no reason to assume that any others have graduated

I'm curious as to where those assumptions came from?
