From what it sounds like, he’s not saying the algorithm is compromised itself, but rather that NIST is recommending a weaker version of it as sufficiently safe at (possibly) the request of the NSA. If that is the case we would know for sure pretty quickly once DISA updates their STIGs for internal use to include quantum resistant encryption. If the STIGs say to use a stronger version than NIST recommends then he was probably right.
