Vice President Pence is trying to win over conservative Republicans with a new health care plan, and that has Republican moderates upset.
A new proposal from the White House and GOP leaders to revive ObamaCare repeal is facing pushback from centrist Republicans who were already wary of the legislation.
Seeking to win over conservative holdouts, Republicans have talked about redesigning their healthcare bill so that states can apply for waivers on two central ObamaCare rules.
The first regulation, known as essential health benefits, requires insurance plans to cover services such as mental healthcare and prescription drugs. The second, known as community rating, prevents insurers from charging higher premiums to people with pre-existing conditions.
Conservatives have long argued that the two regulations drive up premiums, and some of them have reacted favorably to the waiver proposal.
