See also Kamala Harris (first female VP of color! Wow!!!) and Karine Jean-Pierre (she's black AND lesbian!!!), both were chosen for diversity reasons and are completely incompetent at their jobs.
I think it’s a low blow to suggest that either were hired to virtue signal diversity.
I much prefer a later comment where you attempt to lay out a case why he was bad at his job for things he did or didn’t do. Well at least that’s what I think the sources you provided did.
I've heard far dumber things said and no culpability so I imagine nothing to change.

I will say though, at least he did finally show up. Better late than never I guess. His boss doesn't have any plans to.
