US Senate Majority Leader Mitch McConnell is aiming to send a revised version of his healthcare bill to the Congressional Budget Office as soon as Saturday as he continues to push for a vote before Congress's August recess.
The effort reflects the tight timeline McConnell faces in his attempt to hold a vote in July - and the pressure he is under to make changes to the bill that will garner enough support to pass.
With both conservatives and centrists pushing different policy solutions, Senate leaders were still struggling to craft a rewrite of the Affordable Care Act that would attract votes without torpedoing the CBO's official score of how the legislation affects coverage levels and federal spending.
In between closed-door lunches and meetings with McConnell and his team, a number of Republicans flashed visible signs of of frustration even as they expressed reluctant optimism that a vote was still possible.
