Lawmakers are at an impasse on a measure to fund the government, which has been shut down for nearly two weeks. They are also working against an Oct. 17 deadline for raising the nation's borrowing limit. 

The Treasury Department and White House have warned that if the limit is not lifted, the government could default on its debt and cause another economic recession.

Over the weekend, Republicans criticized Democrats for not simply accepting the House budget level, which is nearly $80 billion less than what Senate Democrats proposed and passed. Democrats replaced some of sequestration cuts with new tax revenue.

Congressional leaders were expected to meet with President Obama on Monday to discuss a possible breakthrough.
