Senate Majority Leader Harry Reid says later this morning the Senate once again will reject a House Republican attempt to tie an emergency government spending bill to making changes in the health care law.
Debate on Capitol Hill went well past midnight - the deadline to reach a spending agreement or the government would partially shut down.
People classified as essential government employees will continue to work as the federal government experiences a partial shutdown.
That covers air traffic controllers, Border Patrol agents and most food inspectors.
Government workers such as those at national parks and museums are being told to stay home.
The self-funded Postal Service will continue to operate and the government will continue to pay Social Security benefits and Medicare and Medicaid fees to doctors on time.
