I think it would be awesome if Donald held an online rally while he was in quarantine. The reason being is that I think if he did that the ratings would be higher than the NFL, NBA, and CNN combined.
Also, I just donated $100 to Trump’s campaign. God speed fellow pedes.
The rally wouldn't be at the White House, though. It would be on the Internet. By the interpretation you're using, the President would need to leave his home every time he gets on a campaign conference call.
