Aiming to cast the plan as a victory and in part assuage the president, Republicans described the sum as a "down payment" on Trump's border wall. The funding proposed this week is only a chunk of the $5.7 billion the president demanded before the wall dispute caused a record 35-day shutdown during December and January.
Here are some of the sprawling bill's other provisions, according to the House and Senate Appropriations Committees:
- The plan would put $22.5 billion total toward border security. Trump cheered that figure earlier this week.
- The $1.375 billion set aside for barriers is expected to cover 55 miles of new fencing.
- It "establishes Congress's intent" to reduce total Immigration and Customs Enforcement Detention beds from 49,060 to 40,520, the amount set out by Congress last year, according to a House Democratic summary. Democrats did not get their wish to cut the number of detention beds for interior enforcement.
- It would include funds for more border security agents, customs officers, immigration judges and technology to detect drugs and weapons.
- The legislation would give federal workers a 1.9 percent pay raise. Trump previously proposed a pay freeze for those employees.
- The plan would boost U.S. Census spending by $1 billion over last year.
- It would direct $17 billion toward improving infrastructure such as roads, bridges and airports.
The legislation is expected to pass both chambers of Congress. Republican and Democratic leaders have backed it.
"Here we are with a solid deal in front of us. ... Later today, I hope each of my colleagues will join me in moving forward with the agreement produced by this hard work, and the president will sign it into law," Senate Majority Leader Mitch McConnell, R-Ky., said on the Senate floor Thursday morning.
House Democratic Caucus Chairman Hakeem Jeffries, D-N.Y., said Wednesday he expects an "overwhelming majority" of House Democrats to support the plan.
On Wednesday night, the top appropriators in both chambers, Sen. Richard Shelby, R-Ala., and Rep. Nita Lowey, D-N.Y., urged lawmakers to pass the plan. Both also aimed to paint the proposal as a victory.
In a statement, Shelby said: "This legislation makes a significant down payment on the border wall and provides a bipartisan path forward" to funding the government for the rest of the fiscal year. In her statement, Lowey said: "This agreement denies funding for President Trump's border wall and includes several key measures to make our immigration system more humane."
On Wednesday, Trump appeared to accept the deal and claimed he will build the barrier even if Congress does not approve his desired funding. "A shutdown would be a terrible thing," the president said.
He has repeatedly contended he can redirect money from other agencies to fund the wall. He has also threatened to declare a national emergency to circumvent Congress to build the barrier.
"Regardless of Wall money, it is being built as we speak!" the president tweeted on Tuesday.
