"I can not support a piece of legislation that takes insurance away from tens of millions of Americans and hundreds of thousands of Nevadans", said Heller. The language of the bill will likely change before that vote and it is not clear if the legislation will garner sufficient support among Senate Republicans to pass. Erasing Obama's law has been a marquee pledge for Trump and virtually the entire party for years.
But while it's true that health care costs are rising, there's little evidence that Senate Republicans' bill, which was negotiated in secret for weeks and could see a vote as early as Thursday, would do anything to stop that rise.
"Senator Durbin doesn't want to talk about the fact that in IL they are way down on the number of people even selling insurance and prices are way up", he also said.
The CBO had found that the House bill would kick 23 million Americans off their health plans, making it unpopular with the public.
"No argument against Trumpcare is more eloquent than the grave consequences it means in people's lives", she wrote colleagues.
The Nevada senator joins four other Republicans in expressing opposition to the draft bill as it is now written. Ted Cruz of Texas, Rand Paul of Kentucky, Mike Lee of Utah and Ron Johnson of Wisconsin. The bill also makes major cuts and structural changes to Medicaid, a health insurance program relied upon by almost 75 million Americans - primarily low-income, disabled, and elderly.
"Well, they are also four good guys and they are four friends of mine", said Trump.
"For my part, I'm very concerned about the cost of insurance for older people with serious chronic illnesses and the impact of the Medicaid cuts on our state governments, the most vulnerable people in our society, and health care providers such as our rural hospitals and nursing homes, most of whom are very dependent on the Medicaid program".
Amid the scrum, there are signs Republican opposition is only growing. While McConnell's bill curtails the program at a slower rate than the House version, it ultimately cuts deeper, which has prompted senators whose states expanded Medicaid to raise red flags.
Lawmakers in Washington are still reading through the finer details of the Senate GOP's new healthcare bill, but opponents are already warning it'll give states an impossible choice-either cut services, or spend billions more on healthcare.
The Senate bill also calls for a tighter cap on federal spending in Medicaid overall than the House bill did. Those additional funds would continue through 2020, then gradually fall and disappear entirely in 2024.
Democrats have sharply criticized both versions as a giveaway to the wealthy that would leave millions without health insurance. And it would keep more of Obamacare's insurance regulations than the House legislation.
Washington state officials say about 700,000 Washingtonians could lose health coverage under the Senate plan.
