A cocktail of monoclonal antibodies taken by President Donald Trump during COVID-19 treatment at the hospital was developed using human cells derived from an aborted fetus.

According to Trump’s personal physician, Dr. Sean Conley, the president received a high-dose infusion of monoclonal antibodies last Friday as part of his treatment for COVID-19 infection.

One of the treatments made available to Trump would have been defeated by his own efforts to thwart the scientific research that made it possible: fetal cell tissue from abortions.

The drug developed by Regeneron has not been approved.
