Their decision means Republicans in the Senate are well short of having the support to pass their legislation and raises serious questions about whether President Trump will reach his goal of ending ObamaCare.

In announcing their opposition to the Senate draft, Moran and Lee both said the bill failed to do enough to lower premiums.

"This closed-door process has yielded the [bill], which fails to repeal the Affordable Care Act or address healthcare’s rising costs. For the same reasons I could not support the previous version of this bill, I cannot support this one," Moran said in a statement.

He added that the Senate "must now start fresh with an open legislative process," an indication that relatively minor changes to the current bill would not be enough to win his support. It may also indicate he wants hearings on a bill, which were absent from the process on the current measure.

Highlighting the challenges faced by McConnell, Lee argued the measure is not conservative enough, tugging in the opposite direction from moderates.
