ALBUQUERQUE, N.M. (AP) — City and state officials have decided to postpone Saturday’s planned Martin Luther King Jr. march in Albuquerque because of the increasing number of COVID-19 cases. Officials said the in-person event was being postponed out of an abundance of caution. They also said a Federal Emergency Management Agency bus will still be at Civic Plaza to administer vaccines and on-site testing. In another development, the University of New Mexico starting Tuesday will require face coverings worn by students and employees to be of more protective medical or health grade. The stiffened mandate will require three-ply or better medical and health procedure masks.
