As lawmakers return to Washington, D.C., Congress faces a high-stakes end-of-the-year session. While Democrats will keep control of the Senate, Republicans could secure a slim majority in the House once the final midterm election results are confirmed. Several major items are on the to-do list, including passing a year-end spending bill to keep the government open past December 16, raising the debt ceiling, expanding Ukraine aid, waiving pending Medicare cuts, and offering additional inflation relief. In addition, Senate and House leadership could change in time for the new session starting next January.
