Is KKG a MAGA only sorority?

There’s a reel of their whole chapter on an instagram account called the young right usa, with a caption saying “the left is trying to erase everything that makes America beautiful”, amongst other things. I’m wondering if this was posted with permission from kappa? It seems weird that they would allow any of their members likenesses to be posted from a random account, especially one that has such creepy comments from old weird men
