I only have the same article you do. I’m just not the one assuming The Atlanta Black Star is the only black-owned media outlet, or that every black owned media outlet was late.

Context would lead me to think there must be at least ten, or this demand would make little sense. But that’s a lower boundary.

Rep. Meeks also called on CNN to “immediately to credential a minimum of ten Black-owned media outlets

And also, I would imagine that they aren’t doing this bit of not-enough just for The Atlanta Black Star alone:

Hours before the debate, the Biden campaign will host a press briefing for members of Black-owned media.

There very well could be a legitimate thing going on here, but until CNN says “every black owned media outlet turned in their application late” I’m not going to assume that based off a sample size of one.
