With Trump, you can be sure this is about two things: the election and grifting. It is just a matter of figuring out how, not whether. There’s no “benefit of the doubt” ever deserved with these guys. That ship sailed long ago. The “fix” is always in, regardless of how many lives it costs.
I strongly suspect that this is the last duty that DOD wants to get thrown its way. In some way or another, this is about looking like he’s doing something about the pandemic, finding someone else to blame for the problems that arise, and somehow throwing a spanner into the works. The fewer tests done, the lower the infection rate that is detected (as opposed to the actual disaster), the more Trump and his regime look like they aren’t at the center of the problem.
Nobody, save for a Fox watching wingnut, could believe that these guys are doing a competent, effective job, or care about doing one.
