Bowser demands 14 day "self-quarantine" of travellers/returnees from high virus areas
On the 24th of July, DC Mayor Bowser issued an order demanding that anyone entering or returning to DC from high coronavirus areas such as Florida "self-quarantine" for 14 days. There is no enforcement measure included other than business being allowed to deny service to those who do not comply, and the potential to invoke the Communicable and Preventable Diseases Act. Thus MPD does not appear to be empowered to make arrests for violation of this. It is Possible that Trump knew this was coming and that this is the reason the Jacksonville, FL RNC events have been cancelled.
