“You know, lying in isolation in ICU for seven days, I thought about how wrong I was to remove my mask at the White House. Today, I think about how wrong it is to let mask-wearing divide us,” Christie says in the ad.

The former governor got infected in October after he attended a ceremony at the White House where few people wore masks.
