WASHINGTON — House Republicans scurried on Tuesday to secure the votes needed for a bill that would keep the government financed for the rest of the fiscal year, delaying action by one day to abide by their self-imposed rule to air all legislation publicly for three days before a vote.

The House and Senate are scheduled to vote on the spending plan on Thursday, the deadline before the expiration of a very short-term stopgap financing measure worked out late Friday night. Over the roughly two days between the revelation of the details of the plan early Tuesday morning and the vote Thursday, Republicans and Democrats have the chance to voice their skepticism about the bill.

Representative Jim Jordan of Ohio, who is chairman of the influential House Republican Study Committee, said on Tuesday that he would oppose the measure because it did not cut enough in federal spending.

“While I respect that some of my Republican colleagues will ultimately support this spending deal,” Mr. Jordan said in a statement. “I believe voters are asking us to set our sights higher.”
