The Senate Budget Committee next week plans to consider a budget blueprint that will call for $300 billion in new funding for border security and defense needs, as well as an equal number of offsets.

The move from the Senate Republicans to implement their preferred two-track plan for passing President Trump’s legislative agenda through Congress comes as House Republicans are struggling to coalesce around their own budget blueprint for a much larger package that would also include sweeping tax and spending cuts.

“I’ve always believed that one big, beautiful bill is too complicated,” Senate Budget Chairman Lindsey Graham, South Carolina Republican, said of the House approach. “What unites Republicans, for sure, is border security and more money for the military. It’s important we put points on the board.”

Mr. Graham said his committee will hold a mark-up next week on a budget resolution that will set spending targets of roughly $150 billion each for border security and defense funding to be spent over four years.

Those spending targets will come in the form of budget reconciliation instructions to the committees of jurisdiction to draft legislation that fills out the details on how the money should be spent. Budget reconciliation is a legislative process that allows Republicans to skirt the threat of a Democratic filibuster and pass their priorities along party lines.

Mr. Graham says the border security money is needed in part to hire more Immigration and Customs Enforcement agents to carry out the president’s deportation agenda.

“This plan of the president to deport people and to get rid of the gangs and the criminals is running into a wall of funding,” he said. “So I think it’d be a real mistake for the Republican Congress not to give the Republican administration the money they need to execute the plan.”

The border funding proposal will also include money to finish building the southern border wall, improve technology surveillance along the border and increase detention bed space, Mr. Graham said.

The $300 billion in new spending will be paid for, he said, noting the budget resolution will include instructions to other Senate committees to find those savings.

“That process will take a while,” Mr. Graham said. “Hopefully, you know, not months, but weeks. They’re already working on it.”
