By Wednesday evening, enough Republicans remained opposed to the Senate’s version of the bill to effectively stall its passage in the House.

Even with a handful of holdouts raising objections over cuts to Medicaid or the ballooning deficits, the vast majority of House Republicans have lined up to support President Trump's bill. They say it represents big wins for his agenda by extending tax cuts and adding work requirements for Medicaid.

Senate Republicans can afford to lose no more than three of their own votes on the bill, but two already are opposed and others remained undecided.
