Congressional aides raced on Tuesday to draw up the text of a bipartisan $1.2 trillion spending deal to fund the government through September.

While President Biden, Republicans and Democrats have all endorsed the agreement, they had yet to release its details and it was not clear whether Congress would be able to complete action on it in time to avert a brief partial government shutdown over the weekend.

Still, lawmakers in both parties were already touting what they would get out of the legislation, which wraps six spending measures into one huge package.

“The final product is something that we were able to achieve a lot of key provisions and wins and a move in the direction that we want, even with our tiny, historically small majority,” Speaker Mike Johnson said on Wednesday.

In a closed-door meeting with Republicans on Tuesday morning, Mr. Johnson cited the inclusion of provisions his party wanted, including funding for additional detention beds run by Immigration and Customs Enforcement and cutting off aid to the main United Nations agency that provides aid to Palestinians.

Democrats secured a long-sought deal to create 12,000 new special visas for Afghans who had worked for the United States in Afghanistan; a one-year reauthorization of PEPFAR, the U.S. government’s effort to address H.I.V. globally; and funding boosts for federal child care and education programs.
