The Senate's top Democrat says his chamber will reject a new House Republican plan to avert a partial government shutdown.
The plan would delay President Barack Obama's health care law for a year and repeal a tax on medical devices.
Senate Majority Leader Harry Reid issued a statement Saturday saying House passage of those items will be pointless.
The GOP-run House is expected to act later in the day.
House Republicans plan to attach the proposals to a bill preventing a government shutdown on Tuesday.
Senate Democrats have said before that they will reject changes to the health law, and Obama has said he would veto them if they ever reached his desk.
