Looks like immigration (illegal and legal) total was 11 and most were Trump reversals.. which in any case is not half. So that claim is false.
There was 1 specifically for Advancing Racial Equity. I think it was the very first one. I might also point out that Covid disproportionately effects people of color, so it would seem an argument could be made that the ones regarding covid could have a disproportionately positive effect on black communities.... In any case even if it's just the 1, the less than 1% claim is also false.
What is being implied here is just a dumb argument to make anyway... The % of a given community's votes should not equal the % of Executive Orders about them.
If 100% of the Asian American community voted for Joe Biden, should 100% of his Executive Orders be about them?? No. That'd be ridiculous.
