This week’s investigative journalism roundup highlights significant accountability reporting from across the American press, with major outlets producing investigations on federal use of force, prescription drug pricing, immigration enforcement vetting, antitrust enforcement, precious metals supply chains, and corporate governance. The Investigative Journal monitors these reports for findings that align with public interest oversight and identifies where independent follow-up could deepen the public record.
1. ProPublica and FRONTLINE: “Caught in the Crackdown”
ProPublica, in partnership with PBS FRONTLINE, published a multi-part investigation examining how federal agents have used “less-lethal” weapons during immigration enforcement operations in cities including Los Angeles, Chicago, and Minneapolis. The reporting, anchored by a documentary that aired April 14 and a series of articles that ran through April 20, 2026, reviewed roughly 300 arrest records and concluded that more than a third of the cases had collapsed when contradicted by video evidence or witness testimony, according to the published findings.
The reporting documents instances in which agents deployed tear gas canisters, pepper balls, and chemical sprays in ways that experts cited in the investigation said departed from agencies’ own use-of-force guidelines. One Minneapolis sequence — in which an agent reportedly responded to a thrown snowball by tossing a tear gas canister into a crowd — has become a focal point of the broader narrative.
ProPublica is widely viewed as a left-of-center nonprofit newsroom. For TIJ, the most useful follow-up angles are non-ideological: the underlying after-action reports, body-worn-camera retention policies at participating agencies, and the dismissal data for arrests connected to the operations. Records-based reporting that compares official agency narratives to court dockets would test the central claim that arrests are being filed and then quietly dropped.
2. ICIJ: “Cancer Calculus” — Merck, Keytruda, and Global Pricing
The International Consortium of Investigative Journalists, working with 47 partner outlets in 37 countries, published a yearlong investigation into the pricing strategy behind Merck’s blockbuster cancer immunotherapy Keytruda. According to ICIJ’s reporting, the drug generated $31.7 billion in global revenue in 2025 — nearly half of Merck’s total — while list prices ranged from roughly $80,000 a year in Germany to $208,000 in the United States.
The consortium reported that Merck and affiliated researchers built what it described as a patent “fortress” of at least 1,212 applications across 53 jurisdictions, designed in part to delay generic competition for as long as 14 years past the original molecule’s expiration. The investigation also identifies three documented incidents in Mexico in which counterfeit Keytruda was supplied to public hospitals, with at least one patient death following administration of a counterfeit batch, ICIJ reported.
For TIJ readers, the policy implications cut across partisan lines: U.S. patients pay a multiple of the prices charged in peer economies, and Medicare’s price-negotiation authority — recently extended — will be tested directly against Keytruda. Independent follow-up could focus on FDA orphan-drug designations awarded to Keytruda indications and on the Department of Commerce’s role in the global enforcement of pharmaceutical patents.
3. Associated Press: “Warehouses of Neglect”
An Associated Press investigation published April 28, 2026, examined the “troubled teen industry” — a network of for-profit residential treatment centers, wilderness programs, and therapeutic boarding schools — and the disproportionate presence of adopted children inside it. AP reporters found that adoptees account for an estimated 25 to 40 percent of children in residential treatment despite making up only about 2 percent of American children, according to the data the outlet cited.
The reporting, drawn from court filings, state inspection records, and dozens of interviews, describes patterns of improper physical restraint, inadequate mental-health care, and credible allegations of physical, sexual, and emotional abuse at multiple facilities. AP also reported on a business model in which operators of for-profit boarding schools have specifically marketed services to adoptive families.
AP is a wire service with a reputation for institutional impartiality. The findings are squarely in TIJ’s wheelhouse: state licensing oversight, federal funding flows through Medicaid and the Family First Prevention Services Act, and the role of private equity in residential treatment ownership. State-by-state inspection data and Office of Inspector General audits would form the backbone of an independent follow-up.
4. Associated Press: ICE Hiring and Background Checks
A separate AP investigation, published April 17, 2026, found that some newly hired Immigration and Customs Enforcement officers began work before completing background checks and that records reviewed by the wire service indicated histories of financial, legal, or employment issues among portions of the new cohort. AP reported that ICE recently announced it had completed an unprecedented hiring expansion — adding roughly 12,000 officers and special agents — funded by a $75 billion congressional appropriation.
The investigation does not allege that the agency violated any specific statute, but it raises questions about the pace at which adjudication of background investigations could keep up with the hiring tempo. AP reported that some hires were on the job before formal vetting concluded, citing internal records and interviews.
This is a story where independent follow-up should take precedence over partisan framing. Reporting at TIJ could test the AP findings by filing for the Office of Personnel Management’s contract performance data on the background-check vendor pipeline, by reviewing the ICE Office of Professional Responsibility complaint inflow rates relative to prior hiring cycles, and by examining whether internal “fitness-for-duty” determinations have changed since the surge began.
5. Wall Street Journal: DOJ Antitrust Probe of Major Meatpackers
The Wall Street Journal reported on April 20, 2026, that the Department of Justice’s antitrust division is conducting a criminal investigation into conduct by the country’s largest beef processors, including Tyson Foods, Cargill, JBS USA, and National Beef Packing. According to the Journal, the four firms slaughter about 85 percent of grain-fattened U.S. cattle that move into retail beef channels.
The Journal noted that DOJ officials have not publicly disclosed the criminal nature of the inquiry, and that the existence of any prior civil investigations into pricing practices in the industry has been documented in earlier court filings. No charges have been announced and the companies have not been named as defendants in any related criminal matter at the time of publication.
For TIJ readers, the meatpacking concentration story is well-trodden but consequential — affecting cattle ranchers, grocery prices, and rural economies. Useful follow-up angles include the Packers and Stockyards Division’s docket at USDA, the status of pending civil class actions filed by ranchers, and concentration data from the Government Accountability Office.
6. The New York Times: U.S. Mint and Foreign Gold Sourcing
A New York Times investigation reported in late April 2026 traced gold marketed by the United States Mint as “100% American-mined” to foreign sources, including operations linked to Colombian criminal networks, Mexican and Peruvian pawn shops, and a Congolese mine partially owned by a Chinese state-affiliated entity. The reporting cites a 2024 Treasury Department inspector general audit that, according to the Times, found the Mint had not verified supplier origins for roughly two decades.
The Times reported that illicit foreign gold was commingled with domestic supply at U.S. processors before entering the Mint’s official chain of custody. Treasury Secretary Scott Bessent announced a procurement review in response to the findings, and the Times reported that the Mint adjusted its public marketing language from “100% American” to describing the United States as its “primary” source.
The story is significant on multiple fronts: federal procurement integrity, sanctions and export-control exposure, and the human-rights provenance of materials sold to American collectors. TIJ’s natural follow-up would focus on the inspector general’s underlying audit, the chain of custody at named processors, and any Foreign Corrupt Practices Act exposure tied to upstream suppliers.
7. The Intercept: Palantir’s IRS Contract
The Intercept reported on April 24, 2026, that Palantir Technologies has been paid more than $130 million by the Internal Revenue Service to analyze a wide range of federal databases used in financial-crimes investigations. According to the Intercept, the contract — originally launched during the first Trump administration and continued under the Biden administration — is now operated within the IRS Criminal Investigation division. The report cites contract documents and interviews with current and former officials.
The Intercept reported that the unit’s caseload composition has shifted in recent months, with a reduction in traditional tax-evasion pursuits and an increase in cases involving organizations the publication characterizes as “left-leaning.” The Intercept’s editorial perspective is plainly progressive and skeptical of surveillance technology, which means specific characterizations of intent should be treated as the outlet’s framing rather than established fact.
The underlying procurement and data-handling questions are nonetheless legitimate. TIJ could pursue independent reporting through Federal Procurement Data System filings, Privacy Act system-of-records notices, and IRS Office of Chief Counsel guidance on data-mining tools — all of which would document scope and use without relying on the Intercept’s framing.
8. Reuters: SpaceX IPO Filing and Founder Control
Reuters reported on April 30, 2026, on a previously undisclosed governance provision in SpaceX’s IPO filing, which the wire service reviewed. According to Reuters, the filing states that founder Elon Musk can be removed from his roles as chief executive and chairman only by a vote of holders of Class B super-voting shares — shares that, after the offering, will be controlled by Musk himself, effectively making removal contingent on his own consent.
The Reuters story stands as a corporate-governance investigation rather than a political one. It documents an unusual structure even relative to other dual-class IPOs and raises questions for prospective public-market investors about minority shareholder protections. Reuters has historically been viewed as one of the most institutionally neutral wires in American business journalism.
For TIJ readers, the relevant follow-up is procedural and disclosure-driven: how the Securities and Exchange Commission staff treats super-voting class structures during S-1 review, comparable provisions at peer dual-class issuers, and the proxy-advisor stance from Institutional Shareholder Services and Glass Lewis.
Investigations Aligning with TIJ Beats
Three of this week’s investigations align tightly with The Investigative Journal’s accountability beats and warrant follow-up reporting. The Mint gold-sourcing story sits squarely on the procurement-integrity beat and could anchor a multi-part series on commodity provenance in federal supply chains. The AP “Warehouses of Neglect” investigation merits state-level follow-up reporting on licensing and Medicaid funding for residential treatment programs serving adopted children. And the WSJ meatpacking probe, while early, is the kind of antitrust accountability story TIJ has covered extensively in agriculture markets.
The ICIJ Cancer Calculus reporting also offers a productive avenue: an independent look at how the Inflation Reduction Act’s Medicare price-negotiation list interacts with Merck’s patent strategy. That cross-section of pharmaceutical innovation, federal procurement, and patent policy is one where data-driven reporting can advance the public record without partisan adjudication.
Across all eight investigations, the throughline is that public records — court dockets, inspector general audits, contract files, SEC filings, and licensing registries — remain the most durable basis for accountability reporting, regardless of which outlet originated the story or where it sits on the editorial spectrum. TIJ will continue to monitor these threads and report independently where the documentary record supports new findings.
