WASHINGTON – Senate Majority Leader Mitch McConnell is aiming to send a revised version of his health-care bill to the Congressional Budget Office by as soon as Friday, according to Capitol Hill aides and lobbyists. The effort reflects the tight timeline McConnell faces in his attempt to hold a vote before the August recess – and the pressure he is under to make changes that improve the CBO’s measure of the bill’s impact on coverage levels and federal spending. McConnell is trying to move quickly to produce a new CBO score by the time lawmakers return to Washington in mid-July, giving the Senate about two weeks to fulfill the majority leader’s goal of voting before the August recess. McConnell and his aides plan continue negotiations through the end of the week and will be in frequent communication with the CBO, according to McConnell spokesman David Popp. It remains unclear exactly what parts of the Better Care Reconciliation Act are being revised – or whether McConnell is trying to move the measure to the right, with greater savings or regulatory adjustments, or to the left, with more coverage protections.
