Answer and Explanation:
Martial Law is a state in which a territory is occupied by a country's military forces to restore or impose order under certain emergencies. Some rights such as the right to free transit, speech, and protection could be suspended during the time the Martial Law lasts.
Rumors of Martial Law arose in the U.S. as a result of the COVID-19 Coronavirus spread (2020). Quarantine has been declared worldwide and different countries have imposed Martial Law to control the number people infected by the disease but not particularly in the U.S. In most metropolis it would be necessary since the closest people live the highest the risk of infection but that is not the case of most states in the U.S. Therefore, it is unlikely a Martial Law will be enacted.
