The Senate Homeland Security Committee is poised to take up a second fiscal year 2026 reconciliation package this week, centering on funding for Immigration and Customs Enforcement and Border Security Operations — the two DHS agencies left out of the omnibus appropriations enacted in late April. The markup, scheduled for Wednesday, arrives as congressional Republicans face a narrowing window to secure additional ICE and BSO funding before the current continuing resolution expires.
The context is not new, but the stakes are real. When the House passed its DHS funding bill on April 30, it ended a partial government shutdown that began on February 14 — triggered by disputes over how much to fund immigration enforcement. The measure signed by the President four days later funded most of DHS, but explicitly excluded ICE and BSO. Lawmakers acknowledged then that those agencies would be addressed separately, through reconciliation.
That promise is now being tested. Senate Majority Leader John Thune has publicly committed to moving a second reconciliation bill before the Memorial Day recess, though the legislative path remains tangled. The Senate adopted its budget resolution on April 23 by a party-line vote of 50–48; the House followed on April 29, 215–211. Those resolutions cleared the procedural deck, but the substantive negotiations over funding levels — and which programs get cut to offset new spending — are still unresolved.
The arithmetic is not straightforward. Budget reconciliation rules mean the second package must either find offsetting cuts elsewhere in the discretionary budget or increase the deficit. House Freedom Caucus members have insisted on the former; Senate appropriators have signaled openness to a narrow deficit increase if the cuts are deemed politically untenable. The result is a negotiation that looks less like a typical appropriations fight and more like a whip count in slow motion.
Committee staff briefings are ongoing. According to two sources familiar with the discussions, the current allocation under consideration allocates approximately $12.4 billion for ICE detention and removal operations, and $3.1 billion for Border Security Operations infrastructure and technology — figures that represent modest increases over the FY2025 enacted levels but fall short of the White House’s initial request. The administration has not publicly stated a position on the gap.
The procedural question is whether Wednesday’s markup can produce a bill that can clear the Senate floor with 50 votes — the margin needed under reconciliation — or whether another temporary funding patch becomes necessary. A third continuing resolution for ICE and BSO alone would be politically awkward for a Republican majority that spent weeks attacking the February shutdown as unnecessary.
Fiscal watchdogs are watching closely. The Committee for a Responsible Federal Budget noted in its May 1 tracker that the two-package approach to DHS funding has created “a fragmentation risk” in the overall FY2026 appropriations picture, particularly if the second reconciliation bill fails to pass before the summer recess. Without both packages, total FY2026 DHS spending remains effectively unknown — a condition that complicates both agency planning and congressional oversight.
What happens in the Senate Homeland Security Committee this week will set the parameters for the broader floor fight. The Wednesday markup is the first formal step. Whether it leads to a vote before Memorial Day depends entirely on whether the intra-party negotiations over offsetting cuts can close before the gavel falls.
