A Senate committee is set to hold a hearing Tuesday on the health care overhaul bill.
The House is also set to vote Tuesday on its own version of the bill, though lawmakers are not expected to bring the bill to the floor.
The legislation is expected to garner a majority of support in both chambers, which means Republicans can then move to the Senate floor for debate and vote.
But there is little question that some Republicans will try to prevent that from happening.
A bill that could kill a number of Obamacare regulations is not going to pass the Senate, said Rep. Tom Cole, R-Okla.
Cole said that was one of the main reasons the House’s version of an Obamacare replacement plan did not receive enough votes to pass last year.
Cole, along with other members of the conservative House Freedom Caucus, have lobbied against a vote on the Senate bill, arguing that the Senate version would have far more regulations.
And as lawmakers are moving toward a vote, some Republicans are also pushing for a delay.
Many Republicans have said they want to see a full health care bill before they can consider their own version, a move that could force them to wait until after the 2020 election to approve their own bill.
If the Senate health care plan is approved, a Senate aide said it will be sent to President Donald Trump and Senate Majority Leader Mitch McConnell, R, Ky.
“It’s important to make sure we are able to provide certainty to our citizens and also to help the American people in this effort,” the aide said.
Democrats have been pressing the administration for more time to negotiate with Republicans on the bill.
It is unclear whether they will be able to gain concessions from the administration, which is expected on Tuesday to unveil its own plan to replace Obamacare.
McConnell has been vocal about his desire to pass a health care replacement bill before the election.
As of Monday morning, Republicans were still holding meetings with the White House and the Senate leadership, according to multiple administration officials, but no final decisions had been made.
Rep. Mike Conaway, R., Texas, is a member of the House Freedom caucus, a group that is opposed to the House version of its bill.
But the House has a history of working with the administration on health care.
In 2015, Conaway and other members pushed for a repeal of a key provision of the Affordable Care Act, known as the individual mandate.
That provision, which required Americans to purchase health insurance or pay a penalty, would have been repealed under the Senate plan.
But House Republicans were unable to pass their bill that year.
Rep. Steve Scalise, R.-La., a member in the House leadership team, said that a deal could come soon.
“We’re getting ready to vote on a replacement bill,” Scalise said in a statement Monday.
“We are in discussions with the president and the House on a new, comprehensive bill that can pass both the House and Senate and give Americans a chance to see whether the health-care system is working.”
