The move came despite House Republicans being expected to take the lead on passing a budget bill first. Thune and Senate Budget Committee Chairman Lindsey Graham, R-S.C., also pressed on even after Trump came out in support of the House's proposal, endorsing it earlier this week on Truth Social.
The decision to move forward with the Senate's alternative budget plan, which is two-pronged as opposed to the House's effort to pass one large bill, was blessed by Vice President JD Vance on Wednesday, a source told Fox News Digital.
Trump himself did not seem bothered by their effort either, posting on Truth Social, "Thank you to Majority Leader John Thune, and the Republican Senate, for working so hard on funding the Trump Border Agenda. We are setting records, the likes of which have never been seen before, on stopping criminal illegals aliens from entering our Country. Put simply, we are delivering for the American People, far faster and, more successfully, than anyone thought possible. Your work on funding this effort is greatly appreciated!"

By lowering the threshold for Senate passage from 60 votes to 51 out of 100, reconciliation allows the party in power to skirt its opposition to advance its agenda – provided the items included relate to budgetary and other fiscal matters. The House of Representatives already has a simple majority threshold.
The process is crucial for Republicans, who have a trifecta in Washington, to get key Trump goals accomplished.

House Speaker Mike Johnson, R-La., has claimed that the Senate's first budget bill, along with its two-pronged approach, would be dead on arrival in the lower chamber. He has remained committed to including tax cuts in the bill with border security and other priorities.
The House has managed to move their version through the appropriate committee, but a floor vote has yet to be scheduled.
