Trump is scheduled to deliver a speech Thursday in Charlotte, broadly outlining how he would approach health-care policy in a second term, though the speech is likely to be light on details. Instead, Trump will tout the administration’s efforts to lower drug prices, address surprise medical bills and improve health-care price transparency, according to two senior administration officials and an outside lobbyist familiar with the plans.

He is expected to mostly avoid speaking about repealing and replacing the Affordable Care Act, something he has long promised to do but a position that is ­unpopular with voters.

Advisers also expect Trump to sign an executive order promising to protect people with preexisting conditions as part of Thursday’s event, though the administration has not detailed how this objective could be achieved without the safeguards in President Barack Obama’s signature 2010 health-care law, according to another senior administration official. Experts have said such an executive order would amount to little more than a public relations ploy, and the order is not viewed as a substantive policy proposal among many West Wing advisers.
