Just my 2c on Trump and the jab;
Trump cannot say jab = bad because he instituted the Operation Warp Speed. If he now says jab = bad, then the left will persecute him relentless over this. Just look at what the J6 committee is doing? Imagine if they had a committee that was looking into something that really happened.
Trump cannot say jab = bad or all the bad stuff from the jab will become his fault.
