Obamacare could pay out nearly $1 trillion in subsidies and another nearly $1 trillion for the Medicaid expansion over the next decade if the law remains in place, according to a new projection from the Congressional Budget Office.

The nonpartisan CBO released a report Tuesday detailing the budget outlook for 2017 to 2027. A part of that outlook examined the increases in federal subsidies for paying down the cost of insurance for Obamacare customers and the cost of the law’s Medicaid expansion.
