The battle between congressional Republicans and the White House over the Affordable Care Act is again escalating—in court and on Capitol Hill.

The administration on Wednesday appealed a federal trial judge’s ruling that the government is improperly reimbursing insurers under a program to cover discounts for low-income consumers.

And House Republicans on Thursday began two days of hearings to hammer away at the issue. They released a report that said the administration distributed the funds even though it was aware it needed Congress’s approval.

An investigation by House Republicans argues that the Obama administration is illegally making certain payments under ObamaCare and that officials initially recognized they did not have authority to do so before reversing course.

House Republicans argue that the administration is unconstitutionally making ObamaCare’s “cost sharing reduction” payments to insurers — which help lower out-of-pocket healthcare costs for low-income ObamaCare enrollees — without a congressional appropriation.
