Fact check: What percentage of the ICE budget was allocated to deportation and removal operations during the Trump administration?

1. Why the headline question cannot be answered with a single percentage — the records provided are dollar-focused, not share-focused

The supplied analyses repeatedly emphasize dollar allocations and program increases rather than a single percentage figure for deportation and removal operations. Multiple items note large sums—nearly $30 billion for hiring and deportation functions, $45 billion for detention over four years, or $75 billion to ICE across a four-year span—but none translate those totals into a percentage of ICE’s annual or multi-year budget, nor do they present a consistent baseline ICE total for the same period against which to calculate a share ^{[1] [2] [3]}. The official congressional budget justifications cited outline ICE components such as Enforcement and Removal Operations (ERO) but do not present a simple percentage line item for "deportation and removal operations," leaving an apples-to-oranges comparison problem between advocacy/analysis pieces and granular appropriation documents ^{[4] [5] [6]}.

2. What the analyses actually report — dollar totals, program lines, and ERO mentions

The pieces converge on the claim that the Trump administration-era legislative and appropriations actions funneled very large dollar sums toward enforcement, detention, and deportation capabilities. One analysis cites $29.9 billion toward ICE enforcement and deportation operations and notes ICE’s annual budget increased three-fold ^[1]. Another frames allocations in the "big budget bill" as including nearly $30 billion for hiring and training ICE staff, $45 billion for detention, and $46.5 billion for a border wall ^[2]. A third distills a multi-year package as $75 billion for ICE across four years with roughly two-thirds for detention and $30 billion for arrest and deportation activities ^[3]. Separately, documentation of ERO activity and line items appears in ICE congressional budget justifications, but those documents do not provide a ready percentage that corresponds to the dollar figures cited in the policy analyses ^{[4] [5] [6] [7]}.

3. Why official budget documents and advocacy reports differ in presentation and emphasis

Official ICE budget justifications and DHS appropriations reports structure funding by appropriations accounts and programmatic components (e.g., ERO, HSI, detention) without producing a single “deportation percentage” metric, while advocacy and policy pieces aggregate multiple appropriations and proposed authorizations over multi-year bills to produce dollar totals that fit a narrative about expanded deportation capacity ^{[4] [5] [6] [1] [2] [3]}. This difference in framing yields divergent portrayals: official documents give component-level budgets without a neat percent-of-total summary for removal operations, while policy reports highlight cumulative funding tied to enforcement and removal objectives, sometimes over multiple years, creating large-sounding totals that are not immediately expressible as percent shares without additional baseline calculations ^{[1] [3]}.

4. Reconciling the numbers — what can be reliably stated from the provided material

From the materials provided, one can reliably state that billions were specifically directed toward enforcement, detention, and ERO-related activities during the period in question, and that multi-year legislative packages proposed or authorized substantial increases in those areas ^{[1] [2] [3]}. The ICE FY2020 and FY2021 Congressional Budget Justifications referenced show ERO as a defined component responsible for removals, but they do not present a direct percentage of ICE’s total funding earmarked solely for deportation operations ^{[4] [5] [6]}. Similarly, contemporary advocacy reports quantify multi-year totals and characterize the aggregate effect as a large-scale expansion of deportation capacity, but they stop short of publishing a consistent percent-of-budget figure using the same accounting convention as the appropriations reports ^{[7] [8] [9]}.

5. Bottom line and what additional data would produce a definitive percentage

The bottom line is that the sources here present consistent evidence of substantial, multi-billion-dollar increases in funding for ICE enforcement, detention, and removal-related roles during the Trump administration, but do not provide a single authoritative percentage of ICE’s budget devoted exclusively to deportation and removal operations. To compute that percentage definitively would require (a) a precise definition of which line items count as “deportation and removal operations” (e.g., ERO alone vs. ERO plus detention and supporting units), and (b) the corresponding ICE total budget figure for the identical time frame and accounting basis used by the cited analyses. With those two pieces from the official appropriations documents—line-item totals for ERO and a consistent ICE total for the same fiscal years—a clean percentage could be calculated ^{[4] [5] [6] [1] [3]}.
