The National Association of Insurance Commissioners has filed a lawsuit in California challenging the President’s health care proposal.

The claim is the first legal challenge to Obama’s signature law.

The lawsuit argues the proposal violates federal law because it fails to provide universal health insurance coverage to everyone regardless of age or income.

The complaint was filed on Tuesday in U.S. District Court in San Francisco.

The NACIO is a group of insurers representing health insurance companies, hospitals, hospitals and insurers that provide coverage for medical and dental care, prescription drugs and the like.

The group said in a statement that it has been “taken aback” by President Obama’s suggestion that millions of Americans would be left uninsured.

“We strongly oppose this false and misleading claim that millions will be left out of the Affordable Care Act, and we look forward to defending our clients’ rights,” the statement said.

Obama has previously made a number of health care promises in his bid to secure the Democratic nomination for president, including to provide health insurance for all Americans.

In February, he promised to create a “universal health care system” that would cover everyone, including people with pre-existing conditions.

In the weeks after the election, Obama pledged to expand health care coverage for millions of people and has been pressing Congress to fund the government through Sept. 30, a deadline that the administration has said is a long way off.

The Obama administration also has said it will provide more details on its plan later this week, including details on how it will work and how it would cover a broad range of insurance coverage.
