President Obama will rally Senate Democrats to overcome their differences to support an $848 billion health care bill, during a rare Sunday afternoon caucus meeting.
Obama's trip to the Capitol comes at the opening of a critical week, when Democrats must resolve disputes over abortion and a government insurance option, along with other issues, to meet their target of final passage before Christmas.
Democrats said they would look to Obama to help reconcile divisions between liberals and moderates, while reminding debate-weary lawmakers that completing the bill would represent a milestone in the history of the Democratic Party, which has sought but failed to deliver universal health care for 70 years.
