"In the coming days, the Senate will vote to take up the House bill with the first amendment in order being what a majority of the Senate has already supported in 2015 and that was vetoed by then-President Obama: a repeal of Obamacare with a two-year delay to provide for a stable transition period," McConnell said in a statement.

The move means Senate Republicans will try to repeal ObamaCare now, while kicking a replacement until after the 2018 midterm elections.

McConnell will need to overcome procedural hurdles if he wants the Senate to get to a vote on a repeal-only proposal. He'll need at least 51 senators to support getting on the House-passed legislation, which is being used as a vehicle for any Senate action.

And separating the two could force Republicans to get 60 votes — and the support of Democrats — on the replacement legislation.

It wasn't immediately clear when the Senate would try to pass the repeal legislation. The upper chamber is expected to be in session until Aug. 11, when members will leave town until early September.

With four Republican senators opposed to the current GOP bill, McConnell officially closed the door on the legislation late Monday night.

“Regretfully, it is now apparent that the effort to repeal and immediately replace the failure of Obamacare will not be successful," he said.

It remains to be seen if McConnell will be able to wrangle enough support to repeal ObamaCare without a replacement plan hashed out.

Repeal with a delayed replacement was Senate GOP leadership's original plan, which they backed away from earlier this year due to lack of support.

McConnell himself shot down the idea earlier this month, instead warning that Republicans could be forced to work with Democrats to stabilize the insurance market.

"We are going to stick with that path," McConnell said at an event in Kentucky earlier this month. "Failure has to be possible or you can't have success."

But even as McConnell continued to push back against separating ObamaCare repeal and replacement, moving a repeal-only bill gained the support of President Trump and a growing number of conservative senators.

"Republicans should just REPEAL failing ObamaCare now & work on a new Healthcare Plan that will start from a clean slate. Dems will join in!" Trump tweeted on Monday night after Lee and Moran's statements.

Repealing portions of ObamaCare without enacting a replacement could leave 18 million people without health insurance the following year, according to a report released Congressional Budget Office (CBO) in January.

After the elimination of ObamaCare's Medicaid expansion and insurance subsidies, 27 million people would lose insurance, and then 32 million by 2026, the CBO found.

The 2015 measure guts the law by repealing authority for the federal government to run healthcare exchanges and scrapping subsidies to help people afford plans bought through those exchanges. It zeros out the penalties on individuals who do not buy insurance and employers who do not offer health insurance.

The push to separate repeal and replacement comes after some GOP senators used the setback on the Senate bill to instead argue for a bipartisan process, with open hearings.

Moran, in announcing his opposition, also said senators should "start fresh with an open legislative process."
