Spicer said that instead of pointing fingers at Republican lawmakers, Democrats should look closer to home.

Trump has urged the Republican-led Senate to pass a more "generous" bill than that approved by the House, whose version he privately called "mean", according to congressional sources. The group says Vermonters oppose the bill "by a 3-to-1 margin and (it) is the single least popular piece of federal legislation in decades".

Reuters reports that the Democrats took turns to rebuke the closed door meetings that Republicans have been holding to formulate modalities for replacement of Obamacare.

Republicans argue that Obamacare needs to be replaced because it has failed to prevent premiums and other health costs from skyrocketing.

A source stated to TPM, that, in lieu of debating the bill in public, Senate Democrats would be using their platforms to talk on some of the key objections attached to the bill. "The Senate leadership hasn't shared it with most of the Republican members, let alone the Democrats, let alone the hospital association".

Underscoring the differences, a group of House Republicans drafted a letter to send to McConnell later this week expressing "serious concerns" about the Senate proposal. Polls also reveal dismal public support for the House plan.

In that iteration, about 23 million more Americans would be uninsured by 2026 than if Obamacare were to stay intact, according to the CBO.

Defeat of the House-passed bill wouldn't necessarily end the health care debate in Congress, but it would redefine it.

Spicer is also blaming Democrats for being left out of negotiations over a Senate bill that could come to vote next week.

Mr McConnell has made clear that he wants to have a vote on the legislation before senators leave Washington DC for the Fourth of July.

"I want to assure you, before this summer is over".

Rights and Democracy, a liberal group based in Vermont, has publicly asked Scott to speak out against the bill. "Hopefully we'll have 50 votes when that time comes".

Heading into their regular lunches, GOP senators had few new details to provide reporters on their efforts to dismantle the Affordable Care Act, despite reports that leadership was aiming for a vote by June 30. Whether it should be, and what this says about us, is a different question. My constituents are Americans just like the constituents in Republican states are Americans.

"Senate Republicans are hiding their health care bill for one reason only: it's an immoral disaster that will likely take health care away from more than 20 million Americans", Gillum said.

"I've never heard of a more radical or a more reckless process", said Minority Leader Chuck Schumer, D-N.Y.
