ICE Detentions Reach Second-Term High in July, Agency Data Shows

The record monthly total arrives as congressional debate over immigration enforcement funding and detention capacity remains unresolved.

Immigration and Customs Enforcement detained more individuals in July 2026 than in any prior month of the second Trump administration, according to internal agency data obtained by CBS News. The July figure represents the highest single-month detention total since President Trump returned to office in January 2025, per the same CBS News report published August 2, 2026. The precise number of detentions in the CBS News report was not independently confirmed by The Congressional Times at time of publication; the full internal dataset would be the document that resolves that figure.

The record detention total coincides with reported internal disagreement over immigration policy direction. Fox News reported on August 2, 2026 that former Border Patrol Chief Gregory Bovino publicly accused Department of Homeland Security Secretary Markwayne Mullin of undermining mass deportation efforts after Mullin delivered a speech calling for immigration reform. The specific legislative or regulatory proposals Mullin outlined in that speech were not detailed in available public records reviewed by The Congressional Times.

Senate-confirmed in December 2024, Mullin — formerly a Republican U.S. Senator representing Oklahoma — now leads DHS. His confirmation vote, recorded in the Congressional Record, passed along largely party-line margins. Any formal policy directives issued by Mullin would be documented through DHS administrative records, which are subject to Freedom of Information Act requests.

Congressional jurisdiction over ICE detention capacity rests primarily with the House and Senate Appropriations subcommittees overseeing Homeland Security. The most recent enacted DHS appropriations legislation set detention bed funding levels that ICE is legally required to maintain; whether July's detention figures exceed congressionally authorized bed capacity is unknown. The DHS Inspector General and the relevant appropriations subcommittee hearing records would be the documents that answer that question.

What remains publicly unknown includes the precise July detention count from the internal ICE data, the specific immigration reform measures Secretary Mullin described in his speech, and whether DHS has submitted any supplemental funding request to Congress to support expanded detention operations. A formal supplemental appropriations request, if submitted, would appear in the Congressional Record and on the Office of Management and Budget's website.
