He’s just imitating AI judge Randy Jackson, who says that to all the contestants. It’s kind of a show catch-phrase. Obama commits plenty of real sins - attacking him over this is stupid.
The sitting President of the US should not stoop to imitating idiotic “catch-phrases” on a pop TV show. Asking the audience to consider making charity donations is fine ... but do it with some “gravitas”. These lame attempts by the Obamas to appear “cool” and “just like one of us” fails miserably ... it’s just another brick in the wall of lies.
Oh. I don't watch the show, so I just took it at face value. It would be a weird thing to say in general.
