WASHINGTON — Lawmakers pushed to enact a massive budget deal Thursday along with a stopgap temporary measure to prevent a government shutdown at midnight. The measure appeared set to sail through the Senate in anticipation of the House sending it to President Donald Trump by day’s end.

House GOP leaders were working to shore up support among conservatives for the measure, which would shower the Pentagon with money but add hundreds of billions of dollars to the nation’s $20 trillion-plus debt.

Hopes for a midafternoon Senate vote were dashed by Rand Paul, R-Ky., who was holding the measure up — for now — in hopes of winning a vote to reverse its spending increases.

House Democratic leaders opposed the measure — demanding a vote to resolve the plight of immigrant “Dreamers” who face deportation after being brought to the U.S. illegally as children — but not with all their might. Other rank-and-file Democrats said they would support the bill, which is larded with money for party priorities like infrastructure and combating opioid abuse.

Republicans pointed to money they have long sought for the Pentagon. “It provides what the Pentagon needs to restore our military’s edge for years to come,” said House Speaker Paul Ryan, R-Wis.
