"Science", we are told, is the foundation of all which the Centers for Disease Control (CDC)--the government agency tasked with protecting the nation's public health--undertakes. Their decisions and recommendations are always guided by science--and presumably not by politics.
How do we know this? They tell us this. They promise us this.
From the CDC's "Pledge To The American People":
Base all public health decisions on the highest quality scientific data that is derived openly and objectively
When it comes to the current COVID-19 (aka "CCPVirus") pandemic, however, they are falling far short of the mark. Many of their decisions and pronouncements lack scientific support or scientific rigor. The latest and most glaring example of this is the hype du jour over the wearing of masks and facial coverings to mitigate the spread of the disease.
