President Donald Trump’s Domestic Policy Council and senior health officials have been meeting privately for preliminary conversations on how to address the expiration of health insurance tax credits, according to a White House official and another person familiar with the talks. Conversations about a White House alternative to Affordable Care Act subsidies, which will expire at year’s end, are in the “early ideation phase,” said a third person familiar with the talks. Like others, these people were granted anonymity to discuss private conversations. Options that administration officials have publicly teased in recent days include giving money directly to Americans to cover health expenses, and subsidizing out-of-pocket costs for low-income people enrolled in the ACA.
