I am embarassed I did not know this, but there is no PARTY AFFLIATED black caucus only the black caucus......for all of congress. I was checking on any Republican affliated group of that nature.

This is from 2010 but you get the idea...

"WASHINGTON (AP) — The Congressional Black Caucus says it will allow two recently elected black Republicans to join the group if they ask.

The all-Democratic caucus had wavered over the issue since Tim Scott of South Carolina and Allen West of Florida were elected last week. Chairwoman Barbara Lee had pointed to the group’s liberal mission statement as a potential point of conflict."

Black caucus says it will welcome Republicans | theGrio

So as the link I supplied hinted, this is strictly about Democrats and they admit how it will be presented.
