Protect Health Care for Retired Public Safety Officers Act of 2019 This bill directs the Federal Emergency Management Agency (FEMA), under the State Homeland Security Grant Program, to require each state to include in its grant application a certification for the protection of health care benefits for retired public safety officers. A public safety officer is a law enforcement officer, firefighter, or an emergency medical services provider whose conditions of employment are determined by a collective bargaining agreement. Such certification must provide that the state will not (1) unilaterally modify or eliminate health care benefits for a public safety officer retiree, or (2) allocate grant funds to a local government or Indian tribe that has not certified to the state that such benefits will not be unilaterally modified or eliminated.
