Mr. Trump takes office grasping a lightning rod of American domestic policy—health care. His party has already begun on the repeal, and potential replacement, of Barack Obama ’s signature health-care law, but the task of reworking a sweeping social program six years into its lifespan is proving messy. Republicans, including Mr. Trump, have put forward various ideas to serve as alternatives to the major provisions of the Affordable Care Act, which extended insurance to millions of Americans but also triggered criticism over rising premiums for some users and insurer withdrawals from the individual market. The party has yet to unify behind a single plan, and it remains unclear how much influence will be exerted by Mr. Trump and his administration and how much they will leave to four congressional committees and other groups of interested lawmakers to hash out in the House and Senate.

With President-elect Donald Trump’s inauguration mere hours away, celebrations in Washington, D.C., are getting underway, and the money — among other things — is flowing. Beginning Thursday and stretching through the weekend, most state societies and a number of players in the health care and pharmaceutical industries are hosting inaugural events.
