"We found that they knew there were safety signals on myocarditis very early on in like January, February of 2021... they hid it, they downplayed it." Senator Ron Johnson (R-WI) tells John Solomon that federal health agencies like the CDC and FDA were aware of potential vaccine-related health risks, such as myocarditis and ischemic strokes, much earlier than publicly disclosed. Sen. Johnson also suggests that the agencies intentionally minimized and ignored signals to prioritize the administration's push for widespread vaccination and bivalent boosters.
