Sure peke,
The African-American unemployment rate did continue dropping under trump (a decrease started under Obama), but all rates of unemployment dropped during that period. Also true of this period is that the gap between white and black unemployment did not close and when the pandemic hit, black unemployment rose faster.
If trump truly wanted to claim that he did anything for African-Americans he would have introduced polices to close that gap.
Now during this pandemic which is hitting the Black community harder than the white one, trump claims we have a testing problem instead of actually having a plan.
But hey, maybe he can pick a fight with the NBA again...
