While this post holds a great deal of wisdom I feel the need to enlighten the forum with perhaps a bit more.
The USADA is not one of the "bad" institutions even if it ends up failing us in this case (in some cases, there is just too much money flying around). The USADA is the American branch of WADA, under the leadership of Dick Pound, which is the doping body that originally brought Lance Armstrong down, and ushered in the contemporary zeal for anti-doping, and the belief that it is egregious enough to warrant it. It is WADA that is there alongside the ITF when Maria Sharapova trips over her own lies about taking meldonium for over a decade to treat a "heart condition", but it is the CAS (Court of Arbitration of Sport) that reduces her sanctions, and lends apologism to her lies. It is WADA that is there hip to hip with the IOC when the Russians abuse the Olympics in unprecedented and disgraceful fashion at Sochi, but it is the CAS that orchestrated their road back to competition in PyeonChang 2018.
WADA/USADA = good guy that is trying
CAS = bad guy that is monkey wrench for corrupt Big Men
The USADA has proved exceptionally inconvenient to the powers that be with their testing, and some of their top draws it has taken out since they have taken over anti-doping responsibilities. Things are a million times better off with them in the sport than if it was left solely to the UFC or "third party" testing bodies that are small outfits dependent on their client to exist; neither would the athletic commissions be any better.
Here’s how much control the UFC actually has over drug testing exemptions

Jones dosen't have a
single test in the database in 2018, so if you see Cormier-Jones scheduled immediately after Cormier-Lesnar, I think you can trust the fanbase-- or at least the integrity of the sport-- has been proper fucked in both cases.
