All the list of grievances that he mentioned were discussed before, and It was clear then that it was almost all an artifice.

Why the Republican Congress Will Soon Have No Black Leaders
Black presence in the GOP has been scarce for a long time. It wasn’t until former Republican House Leader Kevin McCarthy’s very recent push to recruit more Black and brown faces for his party that Black Americans began to see representation within the party.
“When you look at the Democrats, they actually look like America,” McCarthy said back in 2023. “When I look at my party, we look like the most restrictive country club in America.” Things were slowly turning to a more diverse GOP with the elections of the four Black GOP representatives by 2022… Everything changed, however, once President Trump took back the White House.
