C'mon man!.. I don't have to write up a story explaining anything... Why the fuck would they invite her instead of a long list of others that should be going to the white house or wtv.
Calling it now.. they're going to use her to promote the vaccines "safety" and "efficacy" and she will basically parrot wtv is said to her back to the masses of sheeple.
This is the logical answer. She has money, she is a black woman, and she is obviously half intelligent enough to create a successful brand.
She's a fucking twat no doubt. But at least she has some sense of common sense
