The CDC did speak up, you seem to have some issue with the CDC not specifically mentioning Biden, which strikes me as odd since gov't agencies don't generally specifically endorse or critique specific politicians.
Here's specifically what Trump said that lead to people chugging bleach. After uttering these words people started misusing bleach, cleaning supplies and disinfectants to combat covid. In response did the FDA and other numerous health agencies call out Trump? No they didn't.
"And then I see the disinfectant, where it knocks it out in one minute. And is there a way we can do something like that, by injection inside or almost a cleaning, because you see it gets in the lungs and it does a tremendous number on the lungs, so it’d be interesting to check that, so that you’re going to have to use medical doctors with, but it sounds interesting to me."
