Judges across the country have ruled more than 4,400 times since the start of October that US Immigration and Customs Enforcement has illegally detained immigrants, according to a Reuters investigation published Saturday.

As President Donald Trump carries out his unprecedented “mass deportation” crusade, the number of people in ICE custody ballooned to 68,000 this month, up 75% from when he took office.

Midway through 2025, the administration had begun pushing for a daily quota of 3,000 arrests per day, with the goal of reaching 1 million per year. This has led to the targeting of mostly people with no criminal records rather than the “worst of the worst,” as the administration often claims.

Reuters’ reporting suggests chasing this number has also resulted in a staggering number of arrests that judges have later found to be illegal.

Since the beginning of Trump’s term, immigrants have filed more than 20,200 habeas corpus petitions, claiming they were held indefinitely without trial in violation of the Constitution.

In at least 4,421 cases, more than 400 federal judges have ruled that their detentions were illegal.

Last month, more than 6,000 habeas petitions were filed. Prior to the second Trump administration, no other month dating back to 2010 had seen even 500.

In part due to the sheer volume of legal challenges, the Trump administration has often failed to comply with court rulings, leaving people locked up even after judges ordered them to be released.

Reuters’ new report is the most comprehensive examination to date of the administration’s routine violation of the law with respect to immigration enforcement. But the extent to which federal immigration agencies have violated the law under Trump is hardly new information.

In a ruling last month, Chief Judge Patrick J. Schiltz of the US District Court in Minnesota—a conservative jurist appointed by former President George W. Bush—provided a list of nearly 100 court orders ICE had violated just that month while deployed as part of Trump’s Operation Metro Surge.

The report of ICE’s systemic violation of the law comes as the agency faces heightened scrutiny on Capitol Hill, with leaders of the agency called to testify and Democrats attempting to hold up funding in order to force reforms to ICE’s conduct, which resulted in a partial shutdown beginning Saturday.

Following the release of Reuters’ report, Rep. Ted Lieu (D-Calif.) directed a pointed question over social media to Kristi Noem, the secretary of the Department of Homeland Security, which oversees ICE.

“Why do your out-of-control agents keep violating federal law?” he said. “I look forward to seeing you testify under oath at the House Judiciary Committee in early March.”
