Republican senators are considering moving forward with a measure to undo President Barack Obama’s Affordable Care Act, or ACA, in the House and potentially pass it in the Senate.

But Senate Majority Leader Mitch McConnell told reporters on Wednesday that he’s not willing to change a law that’s been in place for more than five years.

“We’re going to move forward with the House bill and hopefully the Senate bill as well,” McConnell said.

The House measure would allow Americans with pre-existing conditions to stay on their current insurance plans, while allowing states to waive coverage requirements.

It would also give states the ability to allow insurers to sell skimpy plans to individuals with pre “coverage” requirements.

Republicans, in a move likely to fuel criticism from moderates, want to repeal parts of the ACA that were passed by Congress and passed by the states.

The House measure seeks to repeal the individual mandate and the Medicaid expansion.

The Senate measure would also allow states to offer subsidized health insurance plans.

The bill has not yet been formally introduced.

McConnell said the House measure will be ready for debate in the coming days.

The Senate version will be available for review and amendments in the next several weeks, McConnell said, adding that the House’s plan will likely get its final votes in the spring.

Republicans have a narrow 52-48 majority in the chamber.

The GOP-controlled Senate would need a simple majority to pass a bill with the 60 votes needed to overcome a filibuster.

The bill has to be approved by a majority of the Senate’s 45 members to be signed into law.

McConnell said that if the Senate passed the bill, the Senate could vote on a repeal of the mandate later this year.

The health care legislation, which was backed by more than half of Republicans, faces a difficult path in the GOP-led House, where Democrats have said they will block the measure.
