Because it's not the "Trump vaccine" and they all know it....That gene altering poison was already in the pipe waiting for a half-assed reason to be unleashed long ago.Why would someone else's leftist moderators care if Kennedy exposed the Trump vaccine for what he thinks it is?
I suspect right wing moderators would not allow this info out to protect Trump from the legacy of his vaccine.
RFK jr knows this, so that angle of attack would blow up in the media's face.
