I think she's joking about how people over-report his trivial shit. But it can be read as blithely ignoring the monstrous crimes Obama did commit while in office, because it echoes a lot of the liberal apologia of the administration that amounted to "The worst thing Obama ever did was wear a tan suit".

You're reading it wrong, she's stating you can't make a moral equivalence between Obama and, say, Trump or something because supposedly the worst things obama did were silly.
