NIAID bars U.S. disease scientists from communicating with the WHO during active outbreaks

A May 18, 2026 internal directive from a senior National Institute of Allergy and Infectious Diseases official, obtained by CNN, restricted U.S. infectious-disease researchers to attending World Health Organization meetings only in groups of three or fewer and only in a "listening capacity," with any research questions or countermeasure ideas routed through HHS's chain of command. The limits were imposed during active Ebola and Hantavirus responses; current and former officials called barring direct scientist-to-scientist coordination during an emerging public-health emergency unprecedented.

US State Department adds Central African Republic to its third-country deportation program

The U.S. State Department has negotiated an agreement for the Central African Republic to receive migrants of other nationalities deported by the United States — the latest expansion of the Trump administration's third-country deportation program. Rights groups and Senate Democrats say the program removes migrants who had secured immigration-court protections against repatriation, routing them to unrelated countries to circumvent those protections. The deal was struck at a May 18, 2026 meeting in Bangui led by State Department deputy assistant secretary Christian Jové Ehrhardt and reported by Reuters on June 7; a federal judge's May 22 restraining order shows US officials had already planned to remove a Turkish national to the country on May 26.

ICE agents enter Tucson home without judicial warrant and arrest DACA recipient Karla Toledo

On the morning of May 18, 2026, federal immigration agents arrested Karla Toledo, a 31-year-old longtime Tucson, Arizona resident and DACA recipient, at her home. Video shared by her family shows occupants repeatedly asking agents to produce a warrant, and her family and attorney say no judicial warrant was presented before agents entered. U.S. Immigration and Customs Enforcement confirmed Toledo was taken in a "targeted immigration enforcement operation" and, with the Department of Homeland Security, asserted that DACA confers no legal status, that she entered the country unlawfully in October 2024, and that she assaulted an agent — claims her attorney disputes, citing surveillance footage. Toledo was moved to ICE detention in Eloy, Arizona, where her bond was set at $1,500 and her attorney expected her release within days.

Trump administration proposes reserving 10,000 added refugee slots for white South Africans

On May 18, 2026, the State Department sent Congress an emergency determination proposing to raise the fiscal-year 2026 refugee admissions ceiling from 7,500 -- the lowest in U.S. history -- to 17,500, with all 10,000 additional slots reserved for white South African Afrikaners. The department justified the carve-out by citing an "emergency refugee situation" of race-based persecution, a characterization the South African government rejects. The expansion advances while U.S. refugee admissions from other countries remain effectively frozen: of the 6,069 refugees resettled between October 2025 and the end of April 2026, 6,066 were South African.

ICE arrested immigrants at three Manhattan federal courthouses for over a year without internal legal authority, a federal judge found

On May 18, 2026, U.S. District Judge P. Kevin Castel (Southern District of New York) issued a 15-page stay barring U.S. Immigration and Customs Enforcement from arresting most immigrants inside or around three federal courthouses in lower Manhattan — 26 Federal Plaza, 201 Varick Street, and 290 Broadway — except in narrow circumstances involving imminent national-security or public-safety threats. The court's findings document the underlying abuse this entry records: ICE had conducted courthouse arrests at substantial scale for over a year despite, as federal prosecutors admitted in March 2026, having no internal agency rules establishing the legal authority for the practice, and the agency had continued the arrests after conceding this to prosecutors. A masked-agent arrest was witnessed at 26 Federal Plaza on the morning of May 18, hours before the stay took effect.

Supreme Court declines to resolve VRA Section 2 private-right-of-action question, leaving private enforcement in circuit-split limbo

On May 18, 2026, the U.S. Supreme Court issued two brief, unsigned grant-vacate-and-remand orders in Bd. of Election Comm'rs v. NAACP (5th Cir.) and Turtle Mountain Band v. Howe (8th Cir.), sending both cases back to lower courts "in light of" the Court's April 29, 2026 decision in Louisiana v. Callais. Both cases had squarely presented the question of whether private parties — voters and civil-rights organizations — retain a right to sue under Section 2 of the Voting Rights Act. By declining to resolve that question, the Court leaves in place a circuit split: in the 5th Circuit private suits are allowed, in the 8th they are not. Justice Ketanji Brown Jackson dissented from both orders, writing that she would have decided the cases on the merits to confirm a private right of action.

Federal agencies refused records to the DOGE data-access oversight investigation; GSA blocked inspection of converted offices and a Starlink install

The Washington Post reported on May 18, 2026 that multiple federal agencies are refusing to produce records for an active oversight investigation into how the Department of Government Efficiency (DOGE) obtained access to sensitive federal data and systems. At the General Services Administration, senior officials blocked investigators from examining at least six offices DOGE had converted into bedrooms and from inspecting Starlink satellite equipment installed at the agency. The pattern of refusal sits on top of a January 2026 dismantling of the executive branch's principal internal oversight infrastructure — the dismissal of 18 inspectors general and the heads of the Office of Special Counsel and Office of Government Ethics — which removed many of the watchdogs that would otherwise have compelled compliance.

DOJ moved to drop foreign-bribery and fraud charges against Gautam Adani after his $10 billion U.S. investment pledge

On May 18, 2026, the U.S. Department of Justice asked U.S. District Judge Nicholas Garaufis to dismiss the criminal fraud and foreign-bribery charges against Indian billionaire Gautam Adani, saying it had decided "in its prosecutorial discretion, not to devote further resources" to the case. The move followed Adani's pledge of a $10 billion U.S. investment, which he said he could not proceed with while the case continued, and his hiring of Robert J. Giuffra Jr., one of President Trump's personal attorneys. The Biden-era indictment had accused Adani of bribing Indian officials to win solar-energy contracts while raising billions from U.S. and international investors.

DOJ created a $1.776 billion 'Anti-Weaponization Fund' to settle Trump's $10 billion lawsuit and related claims against the federal government

On May 18, 2026, the U.S. Department of Justice announced the creation of a $1.776 billion "Anti-Weaponization Fund," financed through the federal Judgment Fund, to compensate individuals who allege they were unfairly targeted by the federal government on "political, personal, or ideological grounds." The fund was established as part of an agreement under which President Trump, his two adult sons, and the Trump Organization dropped a $10 billion lawsuit against the IRS over the 2019 leak of Trump's tax returns, along with related damages claims arising from the 2022 Mar-a-Lago search and the Russia- collusion investigation. The president and co-plaintiffs receive a formal apology and no direct monetary damages; the $1.776 billion instead flows to a class of beneficiaries — Trump's broadly stated "allies" — selected by the DOJ.

Trump demanded a DOJ investigation into Maryland's mail-ballot error and blamed Gov. Wes Moore for alleged fraud

On May 18, 2026, President Trump publicly demanded that the U.S. Department of Justice investigate Maryland's mail-ballot administration and blamed Democratic Governor Wes Moore, claiming without evidence that Moore had allowed the problem "in order to make sure that Democrats win." The underlying incident was a vendor coding error, disclosed publicly by the Maryland State Board of Elections, that sent roughly 400,000 voters primary ballots for the wrong party; state officials said no illegal ballots were distributed or counted. Moore's office called Trump's fraud accusation "false and irresponsible."
