"Speaker of the House John Boehner, R-Ohio, returns to his office after an 8:45 p.m. vote on the continuing resolution, at the Capitol in Washington, Monday, Sept. 30, 2013. The Republican-controlled House and the Democrat-controlled Senate are at an impasse as Congress continues to struggle over how to prevent a possible shutdown of the federal government when it runs out of money. President Barack Obama ramped up pressure on Republicans Monday to avoid a post-midnight government shutdown, saying that failure to pass a short-term spending measure to keep agencies operating would ""throw a wrench into the gears"" of a recovering economy.
