With the ball back in its court, the House is returning to work today in hopes of finding a way to prevent a government shutdown. The weekend session comes after the Senate sent legislation back to the House that would keep the government operating until Nov. 15, but without a House provision to defund the Affordable Care Act, also called "Obamacare." If Congress doesn't pass a short-term funding bill by the end of the day on Monday, it would mean the first partial government shutdown in almost 20 years.
A government shutdown would have varying degrees of impact on government agencies and services. Federal air traffic controllers and airport screeners would remain on the job and Social Security, Medicare and unemployment benefits would still go out. But other services would be suspended or curtailed. All national parks would be closed, as would the Smithsonian museums.
