Majority Leader John Thune announced that the Senate will vote on a Republican-led measure alongside a Democratic bill to extend expiring tax credits.

Millions insured through the Affordable Care Act are facing higher health insurance costs in the new year, and Senators have yet to identify a bipartisan solution.

A vote on the possible extension of Obamacare subsidies was a key part of the deal to reopen the federal government last month, which ended the longest government shutdown in American history. Senate Democrats proposed a three-year extension last week on the subsidies that are set to expire at the end of the year.

The Senate is set to vote on a Democratic health care proposal this week, a key tenet of the deal to end the government shutdown.
