On Wednesday, Fox News anchor Chris Wallace disapprovingly spoke of President Donald Trump‘s COVID-19 diagnosis and warned the public to wear masks.

He told viewers “wear the damn mask” and to “follow the scientists.”

The presidential debate moderator recalled that the Cleveland Clinic required for debate attendees to wear masks. He noted that the First Family did not wear masks despite clinic staff offering them masks. The family waved the staff off and proceeded without masks on.

Later on, Wallace criticized Dr. Scott Atlas, Trump’s COVID-19 adviser, who has championed the idea of “herd immunity.”
