Senate Republicans’ bill to replace the Affordable Care Act is facing pushback from four of the chamber’s most conservative members, who have banded together to enhance their negotiating position.

Senate Republicans plan to release a health care bill that would curtail federal spending, reform Medicaid, repeal taxes on the wealthy and eliminate funding for Planned Parenthood as part of an effort to make good on their campaign promise to repeal the Affordable Care Act. The bill is expected to largely mirror the House version, but with some significant differences.

Opposition to the House GOP health care bill has nearly doubled among Republican voters from 16 percent at the end of April to 30 percent in June. Among all voters, disapproval of the bill has soared to 50 percent, up from 37 percent at the end of April.

Senate Majority Leader Mitch McConnell could have the Senate vote next Thursday to repeal and replace the Affordable Care Act. The full text of the bill is expected to be released this week, and a score from the Congressional Budget Office could come early next week.

Senate Democrats are weighing whether to use parliamentary maneuvers to prevent the Senate from conducting routine business in an effort to protest the GOP health care push.

Majority Leader Mitch McConnell (R-Ky.) is still aiming for a floor vote to overhaul the nation’s health insurance system before the July recess, even though major disagreements among Senate Republicans, particularly over Medicaid, threaten to derail the GOP’s efforts.

Senate Republicans may provide higher federal funding to states with low Medicaid costs in their health care bill, as they mull how to equitably treat states that chose to expand the program under the Affordable Care Act and those that declined it.

Despite GOP claims that the Obamacare markets are in a “death spiral,” Centene announced that it would offer plans in three new states for the first time, as well as expand its offerings in six states where it currently sells insurance.

The Supreme Court ruled to cut the time that it takes for copycat versions of biologic drugs to enter the market.
