How many confirmed cases of U.S. citizens detained by ICE were documented in the GAO review and what were their outcomes?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
The GAO’s recent review found that ICE arrested 674 individuals whom its records flagged as potential U.S. citizens, and of those, 121 were recorded as detained in ICE facilities and roughly 70 were subsequently deported, according to GAO’s analysis and summaries cited in reporting [1] [2] [3]. The GAO also warned that ICE’s data are incomplete and inconsistent, meaning these counts likely understate the true scope and complicate firm conclusions about outcomes for U.S. citizens and presumed citizens [4] [5].
1. What the GAO counted: arrests, detentions, deportations
The GAO analysis identified 674 arrests of people whose records indicated they might be U.S. citizens, and from that pool it documented 121 individuals who were recorded as having been detained in ICE facilities for one day or more and about 70 people who were deported during the period reviewed, figures that GAO-derived reporting and advocacy groups have repeatedly cited [1] [2] [3]. GAO’s methodology counted “initial book‑ins” differently from ICE’s public reports — GAO included initial bookings into ICE facilities and temporary sites that ICE excludes from its public tabulations — which produced higher totals than ICE’s own public summaries [4] [5].
2. Outcomes for those detained: removal, release, and data gaps
Among the detained cohort GAO identified (121 people), the most concrete documented outcome cited in public summaries is that about 70 were deported, meaning GAO’s analysis found dozens of cases where people flagged as potential U.S. citizens nonetheless were removed from the United States [1] [2]. GAO cautioned, however, that ICE’s recordkeeping omissions and varying practices for issuing detainers and tracking citizenship investigations prevent a full accounting of whether those deported were later confirmed U.S. citizens or whether some detentions and removals resulted from administrative errors [6] [5]. The agency therefore framed these numbers as minimums, not definitive counts, because ICE “does not know the extent to which its officers are taking enforcement actions against individuals who could be U.S. citizens” [2].
3. Historical context and earlier GAO findings
This is not the first GAO review to flag problems: a 2021 GAO product found that ICE had issued detainers for at least 895 potential U.S. citizens and that ICE’s processes for investigating citizenship before issuing detainers were uneven, underscoring a persistent pattern of misidentification and weak tracking that predates the more recent data snapshot [6]. GAO’s 2024 enforcement review and its facility‑inspection review both emphasize that the underlying data systems and agency reporting practices have not been sufficiently robust to answer basic questions about who is being arrested, detained, and removed — including whether U.S. citizens are mistakenly caught up in enforcement [4] [7].
4. How to interpret the numbers and competing narratives
The raw counts — 674 arrests, 121 detained, 70 deported — are striking but must be viewed through GAO’s caveat that ICE understates or inconsistently reports detention figures and that GAO’s reconstructed totals are minimum estimates, not a definitive census [4] [3]. Advocates and media outlets have used GAO’s figures to argue that ICE has deported U.S. citizens and that the problem is systemic, while the agency and some policymakers point to efforts to improve identification practices; GAO’s own central finding is procedural: weak data and unclear processes hamper reliable oversight [1] [4]. The possibility of higher, uncounted cases remains open because GAO could only analyze the records available to it and ICE’s own reporting practices exclude some initial bookings [5].
5. The practical takeaway for oversight and accountability
GAO’s documented counts—121 detained and about 70 deported from the flagged group—provide an evidentiary baseline that is alarming in its own right and which the watchdog says demands fixes to ICE’s data systems, clearer procedures for citizenship investigations, and better tracking of detainers and outcomes so that future oversight can determine how many confirmed U.S. citizens were wrongly detained or removed [6] [4]. GAO’s insistence on better measurement is the practical policy prescription: without it, any published totals remain underestimates and adversarial narratives will continue to clash with agency claims about accuracy [7] [5].
