The day after the American Health Care Act (AHCA) was passed in the US House of Representatives, a group of Republican senators are at work on a version they hope will pass in the Senate. The revisions are expected to be so substantial that the senators crafting the legislation are reportedly not even bothering starting with the text approved in the House, and instead will begin by drafting a health care bill from scratch.

The list of 13 senators working on the bill was first reported by Bloomberg and confirmed to Quartz by a Senate aide:

Mitch McConnell of Kentucky

Rob Portman of Ohio

Pat Toomey of Pennsylvania

John Thune of South Dakota

John Cornyn of Texas

Ted Cruz of Texas

Lamar Alexander of Tennessee

Orrin Hatch of Utah

Mike Lee of Utah

Mike Enzi of Wyoming

John Barrasso of Wyoming
