Where can I legally purchase a pet Spotted Hyena in the United States?

I've looked into the legality of this, I've researched hyena behavior and health needs, have adequate space for an exotic pet of this nature, know roughly the cost of keeping one as a pet, and am researching how I can obtain a permit to own a hyena in my state. My main problem is that hyenas are not popular as exotic pets, and I can't find anywhere to purchase one legally after I've gone through all the paperwork and legal matters. If anyone knows where I can legally purchase a hyena cub, that would be of great help. Thank you to anyone and everyone who provides an answer.
