Recently on the campaign trail — like when Trump took the stage at a rally in Waterford Township, Michigan, near Detroit on Friday — the president has pushed a baseless conspiracy theory that “our doctors get more money if someone dies from Covid,” and that they are inflating the Covid-19 death toll because of this. There is, of course, no evidence for either part of that theory — either that Covid-19 deaths are being overcounted in the US, or that medical workers are doing so to profit from a pandemic that has, as of November 1, killed more than 230,000 people in the US.
