Hours before protesters were set to rally against her plans, Gov. Maura Healey on Monday night announced she's pausing her effort to close Pappas Rehabilitation Hospitals for Children and Pocasset Mental Health Center. Opponents of Healey's hospital closure plans planned to rally Tuesday morning on the State House steps and also oppose her plan to lay off 170 Department of Mental Health case managers. Organizers have also planned a legislative briefing and media availability with families and students from Pappas, and the delivery of a petition, signed by more than 17,500 people, to the governor's office.
