President-elect Donald Trump and congressional Republican leaders are promising to make repeal and replacement of the Affordable Care Act one of their highest priorities in the first 100 days after they take full control of the federal government in January.

Just days after a national campaign in which he vowed repeatedly to repeal President Obama’s signature health care law, Donald J. Trump is sending signals that his approach to health care is a work in progress.

This wildest presidential election possibly ever is now in the books. Donald Trump, a man who has never held political office and has no military background, stands ready to head to the Oval Office in roughly two months to become the 45th president of the United States.

Donald Trump’s victory in Tuesday’s presidential election, together with the defeat of a California ballot measure, has one industry breathing a sigh of relief, at least for now: pharmaceuticals.

Hospital and insurance companies that have benefited from the Affordable Care Act’s expansion of Medicaid coverage saw a sharp fall in their stock prices on fears a Trump administration could roll back that expansion.

Millions of low-income Americans on Medicaid could lose their health coverage if President-elect Donald Trump and a Republican-controlled Congress follow through on GOP proposals to cut spending in the state-federal insurance program.
