Trump outsourced the job to Big Pharma. He wrote them a blank check and said "do it fast". Trump does not have any idea what they are or are not actually doing or what kind of testing or long term agenda they have. In one debate Trump said "You don't trust Pfizer, Johnson & Johnson?" The answer is no, not totally i don't. They are big American companies, certainly better than Russian companies, but they still do some shady stuff and they have huge long term profit seeking motives
