New York Gov. Andrew Cuomo on Thursday launched an investigation into nursing homes‘ conduct during the COVID-19 outbreak, which has left more than 3,500 residents of long-term care facilities dead since the start of March.

The state Department of Health and Attorney General Letitia James will co-lead the investigation, which will focus on whether nursing homes and adult-care facilities appropriately followed state law and regulation as the coronavirus went on its torrid spread in New York.
