What's next in the Republican health care push

— -- President Donald Trump and leading Republicans are making last-ditch efforts to try and repeal Obamacare even though there doesn’t seem to be enough support to do so.

The next step comes in the form of a procedural vote that will be held "early next week," as Senate Majority Leader Mitch McConnell announced on the Senate floor Tuesday night.

When that happens, 50 GOP senators must vote yes in order to open up debate on a health care plan that the U.S. House of Representatives passed in May of this year. Then, the repeal-only language that was initially passed and subsequently vetoed in 2015 would be added to the bill as an amendment. The Senate's repeal-only plan would allow for a "stable two-year transition period."

The numbers do not look like they are in McConnell’s favor at the moment, however, as three senators have already come out against the plan to repeal the Affordable Care Act without replacement legislation. It's also unclear if Sen. John McCain (R-Ariz.) will be back in time for the vote next week as he recovers from a craniotomy.

But there are some ardent supporters who have come out in favor of repealing even though they were publicly opposed to the replacement plan.

Sen. Rand Paul, R-Ky., one of the fiercest naysayers of the latest health care bill, is on board with this repeal-only plan.

"I'm in favor of and will vote to go to the clean repeal that is being proposed now," Paul told "Good Morning America" today.

"I still favor a replacement," he added. "But what we discovered is Republicans don't agree on a replacement."

Earlier this week, Paul urged his fellow lawmakers to consider their constituents.

“If you're not willing to vote the same way you voted in 2015, then you need to go back home and explain to Republicans why you're no longer for repealing Obamacare,” Paul said.

Sen. Jerry Moran, R-Kansas, who helped issue the fatal blow to a planned procedural vote on the replacement bill, said he's now in favor of adopting the 2015 plan and repealing ACA without an immediate replacement.

"My hope is that means there are full legislative hearings, that we have determined what can be done to improve access to affordable healthcare across the country. In a sound, fiscal kind of way," Moran told reporters.

Other actions being taken

One lawmaker is taking actions to try and quell any confusion about what happens during the turbulent discussions.

Sen. Lamar Alexander, the chairman of the Senate Health, Education, Labor and Pensions Committee, announced that he will hold hearings on "how to stabilize the individual market," which is a smaller piece of the health care equation that both Democrats and Republicans want to address.

“However the votes come out on the health care bill, the Senate health committee has a responsibility during the next few weeks to hold hearings to continue exploring how to stabilize the individual market. I will consult with Senate leadership and then I will set those hearings after the Senate votes on the health care bill,” Alexander said in a statement.

Trump’s plan moving forward

Trump said Tuesday that he was “very disappointed” in the Senate’s failure to get a health care bill passed.

He added that his new plan is to "let Obamacare fail and then the Democrats are going to come to us."

Trump also said he doesn't think the Republican plan "is dead" but it "may not be as quick as we had hoped but it is going to happen."

The White House invited all 52 Republicans over for lunch today in an effort to help the party come together on the health care issue.

"I will be having lunch at the White House today with Republican Senators concerning healthcare. They MUST keep their promise to America!" he wrote.

"The Republicans never discuss how good their healthcare bill is, & it will get even better at lunchtime.The Dems scream death as OCare dies!" the second tweet reads.
