The gains in coverage from the Affordable Care Act are starting to decline.

According to a new report from the Center For Disease Control And Prevention--the uninsured rate for American ages 45-to-64 jumped 10.3 percent last year.

That's up a full percentage point from 2017--and it marks the first time a government study has not shown and increase.

The uninsured rate serves as a gauge for President Trump's impact on health care coverage, his administration is seeking to dismantle every aspect of the Affordable Care Act in the courts.

The landmark health care law is credited with extending coverage to millions of Americans.

The uninsured rate did remain stable for younger adults.
