Advocates and health care workers in Massachusetts have expressed concerns that a bill proposed by the Trump administration could dismantle the state's health care safety net, which was established as a model under the Obama-era health overhaul. Massachusetts, known for its successful implementation of Obamacare's framework, has a program that provides insurance coverage, preventive care, and access to lifesaving medications. The proposed legislation has raised fears that these protections and benefits could be undermined, potentially unraveling the health care safety net that many residents rely on.
