A second Senate committee has scheduled a hearing for next week to discuss a last-ditch Republican effort to overhaul Obamacare.

The hearing, scheduled for Monday, will be led by the Senate Finance Committee, which holds jurisdiction over healthcare bills along with the Senate Health, Education, Labor and Pensions Committee.

A second hearing is scheduled for Sept. 26 by the Senate Homeland Security and Governmental Affairs Committee.

The bill would transfer the revenue from Obamacare to states in the form of block grants so they could set up their own healthcare systems. It also would repeal the individual mandate and employer mandates.

"Senators have expressed a strong desire to examine the details of the Graham-Cassidy proposal through a public hearing," Sen. Orrin Hatch, Senate Finance Committee chairman, said in a statement. "A hearing will allow members on both sides of the aisle to delve deeper into its policy and gain a better understanding of what the authors hope to achieve."

The overhaul effort has been billed by its supporters as a move to reignite GOP efforts to repeal and replace portions of Obamacare after a vote failed in July. It was introduced by Republican Sens. Lindsey Graham of South Carolina, Bill Cassidy of Louisiana, Dean Heller of Nevada, and Ron Johnson of Wisconsin, and faces a Sept. 30 deadline for passage to meet a recommendation from the Senate parliamentarian.

Sen. John McCain, R-Ariz., voted against the July bill that would have repealed certain mandates in Obamacare, called "skinny repeal," and has repeatedly called for "regular order" on healthcare, by which he means a bill that would go through hearings, open debate, and amendments from both sides of the aisle.

"We've had nine months to get it done and we haven't," McCain said prior to the Senate Committee hearing announcement, when asked whether there was enough time to get the bill through via regular order. "Is it my problem now that we only have a week?"
