Rising health insurance premiums under Obamacare will continue to hit Americans this year, according to a new report from the Congressional Budget Office.

“High and rising premiums for private health insurance are a matter of concern for [Obamacare] enrollees. They also affect the federal budget, because the federal government subsidizes most premiums—directly or indirectly—at a cost of roughly $300 billion in fiscal year 2016,” the CBO said.
