He's a scientist. Science doesn't give a $#!+ about politics. It's only certain politicians who keep trying to politicize science.
As far as someone else's accusation about Fauci "flip flopping" or "being wrong," science is about drawing the best conclusions that you can with the data that's available. Early on, there was little data about how COVID-19 spreads, so a lot of early conclusions were wrong. As more information came in, the models were adjusted and the conclusions were modified. That's how science works - it's a self-correcting system of progressive discovery. Changing one's mind in the face of evidence is better than doubling down on a flawed conclusion or "hoping" the problem will just go away.
