That previous commitment did not specify that the measure would be attached to the government funding, bill, though, as Alexander now says.

Attaching the measures to the government funding bill sets up a possible showdown with House conservatives, who oppose the ObamaCare measures as propping up the health-care law.

Asked about Alexander's comments, a McConnell spokesman said "the Leader made a firm commitment to Chairman Alexander for action on this by the end of the year." The spokesman did not confirm that this week's spending bill would be the legislative vehicle, though.

"We’re very hopeful that the House will agree to it since most House members already voted for similar provisions in their repeal and replace legislation earlier this year," Alexander said.

The two bipartisan bills would provide funding aimed at bringing down ObamaCare premiums, which Alexander argues would make up for the premium rise from repealing the individual mandate in the tax bill this week.

Senate Democrats, though, are raising the prospect that they could vote against a government funding bill, known as a continuing resolution (CR), that includes the Alexander-Murray bill, arguing that it is not enough to make up for the damage of repealing the ObamaCare mandate in the tax bill.

"We have to judge a whole package but I don’t see a CR loaded up with health provisions passing both chambers," said a Senate Democratic aide.

Alexander appeared confident that his measure would get through the Senate on the spending bill this week.

"The tax bill will include the repeal of the individual mandate; that will push rates up slightly," Alexander said. "Later that week we’ll pass the spending bill which includes Alexander-Murray; that’s the bipartisan bills that will push rates down more in 2019."
