ICE arrested 49,571 illegal immigrants in a single month, the highest total of President Trump's second term, as a massive hiring surge and local police partnerships push enforcement far beyond the southern border.
The July figure marks a 15 percent jump from June's 43,021 arrests and a 70 percent increase from February 2025, when the administration's interior enforcement push was still ramping up. Texas and Florida alone accounted for nearly 20,000 of those detentions, driven largely by a deputization program that lets local officers act as arms of federal immigration enforcement. The data, provided to the University of California, Berkeley, showed a sharp escalation across virtually every region of the country.
Before Trump returned to office in January 2025, ICE arrests hovered around 8,000 a month. Eighteen months later, the agency is pulling in more than six times that number, a transformation fueled by billions in new funding through the One Big Beautiful Bill Act, expanded contracts with the data firm Palantir, and an aggressive recruitment drive that grew ICE's workforce from roughly 21,000 to 29,000 employees.
The administration's most consequential tactical shift may be the expansion of partnerships with state and local law enforcement. Breitbart reported that the number of local agencies participating in the 287(g) program, the federal authority that deputizes local officers to enforce immigration law, has exploded from 135 to more than 1,400 since Trump began his second term.
Those partnerships accounted for roughly 13 percent of July's total arrests, or about 6,500 detentions, up from less than 5 percent a year earlier. Florida credited the program with 15,000 arrests overall. Texas said local officers made approximately 10,000 arrests on ICE's behalf. In Wyoming and West Virginia, deputized local police now account for more than half of all immigration arrests in those states.
The program's reach has not stopped at friendly borders. Arrests doubled in New Mexico and New Jersey, both Democratic-led states that passed laws earlier in 2026 restricting state officials from cooperating with ICE. Vermont and Montana, two sparsely populated states, also saw their arrest numbers double.
Mark Krikorian, executive director of the Center for Immigration Studies, told the AP:
"They changed the tactics and are, if anything, being more effective."
Homeland Security Secretary Markwayne Mullin, the former Oklahoma senator who took over after Trump fired Kristi Noem, told lawmakers at his confirmation hearing that ICE would focus on arresting criminal migrants, "the worse of the worse."
The data tells a different story. Fewer than 4 percent of the migrants ICE arrested in July had a past violent conviction. Most had no criminal charge or conviction at all. That gap between Mullin's stated priority and the agency's actual operations has drawn fire from both the left and the right.
Former Border Patrol chief Gregory Bovino argued in a recent interview with Tucker Carlson that Mullin was undermining mass deportations. Right-wing figures Laura Loomer and Steve Bannon piled on after Mullin said the claim that immigrants steal American jobs holds in some industries but not all, a statement that struck immigration hawks as a concession they did not ask for.
But the arrest numbers themselves undercut the charge that enforcement has gone soft. Newsmax noted that Congress infused ICE with billions of dollars, enabling the agency to hire 12,000 new deportation officers and investigative agents. Whatever Mullin's rhetoric, the machinery is running at full speed.
At the southwestern border, the picture is starkly different from the chaos of the Biden years. Border Patrol has recorded fewer than 10,000 encounters per month since February 2025, the lowest totals in more than 25 years of available monthly data, according to the Pew Research Center.
The administration's enforcement energy has shifted decisively inward. The July arrest spike reflects a strategy built around traffic stops, workplace checks, and the deputization of local police rather than the high-profile urban raids that defined earlier months. The Minneapolis crackdown in January 2026, during which DHS agents shot and killed two American citizens during immigration enforcement operations, became a political liability. Trump fired Noem roughly six weeks later and tapped Mullin within days.
Mullin has kept ICE out of the headlines since then. The numbers, though, have only grown.
ICE released no detention or deportation figures between April 9 and July 24, 2026, a gap spanning more than three months and multiple missed semimonthly reports. The blackout ended just before the July arrest data surfaced, but it left an accountability hole that the agency has not publicly explained.
Marc Rosenblum, the DHS official in charge of publishing immigration arrest and deportation data, resigned in late July after a decade at the agency. In his resignation, he cited a "challenging and often hostile work environment." His office had grown to 45 people under Biden and was downsized under the second Trump administration.
Rosenblum's departure means the official responsible for verifying and releasing the government's own enforcement numbers walked out the door just as those numbers hit a record high. The data itself has become contested ground.
Despite the enforcement surge, public approval of Trump's handling of immigration has eroded. An Economist/YouGov poll conducted in August 2026 found 53 percent of respondents disapprove of the president on immigration, a net rating of minus 13, down from plus 11 at the start of his second term. A separate AP survey put approval at 39 percent and disapproval at 58 percent.
Mike Howell, president of the Oversight Project, captured the frustration on the right in comments reported by Breitbart:
"The numbers remain wildly disproportionately low to the scale of illegals let in by Biden and the promise of mass deportation."
That criticism frames the core tension. Nearly 50,000 arrests in a single month would have been unthinkable under any prior administration. But measured against the millions of illegal immigrants who entered the country during the Biden years, hawks argue the pace still falls short of the promise that put Trump back in office.
The machinery is bigger, faster, and more decentralized than it has ever been. Whether it is big enough to match the scale of the problem is the question that will follow this administration to the midterms and beyond.
