Give it a week or two. They're still getting their talking points. If they could embrace Jan 6th with no shame, this will be a non issue in a couple of weeks. And the Dems will just let it fade in to the memory.
I would put money down on them removing Juneteenth as a federal holiday. "DEI" holiday? check. enacted by Biden? check. will trigger the libs? check.
If I could bet on it I'd wager my house.
