I have no idea what a race-based journalist is, so I looked it up. AI says:

A race-based journalist, or more accurately a race reporter or beat reporter covering race, is a journalist who focuses specifically on how race, racism, and identity impact society, politics, and culture. They work to uncover systemic inequities often overlooked by mainstream media, providing nuanced narratives on race-related issues.

I seriously doubt anyone at the WaPo wrote about that after Bezos took over in 2013.
