House Republicans are preparing to vote Saturday night on a temporary spending bill that includes a one-year delay for ObamaCare, resulting in the White House saying President Obama would veto such a proposal, almost guaranteeing a government shutdown Monday night.

The House Republican Caucus earlier in the afternoon agreed on the plan – to add to the Senate’s spending bill amendments to delay ObamaCare, repeal the law’s medical device tax and fund the military should Washington fail to agree on a spending bill and the government technically runs out of money Monday night.

The lower chamber votes are scheduled to take place later tonight. The tax on medical devices is one of the administation’s main sources of funding for ObamaCare.
