The Trump administration came in looking to dismantle Barack Obama's health care law, but the Affordable Care Act survived.
Now the administration is on the line to deliver a smooth finale to sign-up season, with a crush of customers expected this week.
Friday, Dec. 15 is the last day for procrastinators to enroll for subsidized private coverage for next year in 39 states served by the federal HealthCare.gov website. Consumer interest has remained brisk, although the Trump administration cut sign-up season in half.
A crunch could slow the website, and lead to long hold times at the federal call center.
Administration officials are saying little about their contingency plans for the final week. But HealthCare.gov has been sending out targeted emails reminding people of the deadline.
