A gunman opened fire at the Teotihuacan archaeological complex northeast of Mexico City on April 20, 2026, killing a Canadian tourist and wounding several others before fatally shooting himself, Mexican authorities said. Officials reported four people were wounded by gunfire and two others injured after falls during the panic; those hurt included visitors from Canada, Colombia and Russia. Security forces recovered a firearm, a bladed weapon and ammunition at the scene. President Claudia Sheinbaum said federal, state and local agencies were coordinating the response and that authorities were in contact with the Canadian embassy. The site, one of Mexico’s most visited cultural attractions with about 1.8 million visitors last year, was evacuated and temporarily closed while investigators processed the Pyramid of the Moon area. Early statements from the State of Mexico described the attacker as acting alone; motives have not been established. Authorities have launched an investigation and increased security at the complex as officials assess how the assailant gained access with weapons and consider tighter entry checks and surveillance measures.

Lori Chavez-DeRemer resigned as U.S. Labor Secretary on April 20, 2026, the White House said, stepping down amid a months-long inspector general probe into allegations of professional misconduct. The inquiry, which Reuters and other outlets reported was nearing completion, examined complaints including an alleged affair with a member of her security detail, use of department resources for personal travel, reports of drinking on the job and inappropriate texts sent to young staffers. Several senior aides had already left or been placed on leave as the probe unfolded. Chavez-DeRemer said she will take a private-sector position; White House communications director Steven Cheung praised her record protecting workers. Her deputy, Keith Sonderling, will serve as acting secretary. Chavez-DeRemer, a former one-term congresswoman from Oregon confirmed as labor secretary in March 2025 by a 67-32 Senate vote, had unusual union support when nominated. The inspector general review also touched on messages involving family members and prior complaints that prompted internal probes; police and prosecutors previously declined to bring charges in at least one matter. Her departure follows recent exits of other cabinet officials and leaves questions about leadership and policy continuity at the Labor Department.

On April 20, 2026 a lone gunman opened fire at the Teotihuacán archaeological complex, one of Mexico’s most visited heritage sites about 40km (30 miles) north of Mexico City. Mexican authorities and multiple news agencies reported a Canadian woman was killed and six other people were injured — four by gunfire and two by falls while fleeing. The shooter later died from a self-inflicted gunshot. Officials recovered a firearm, a knife and ammunition at the scene. Footage circulated showing a man with a pistol on the Pyramid of the Moon and tourists scrambling for cover. Mexico’s president, Claudia Sheinbaum, said federal and state security forces were deployed and that her administration was in contact with the Canadian government. Mexican state security authorities said some of the wounded were Colombian, Russian and Canadian nationals. The site recorded roughly 1.8 million visitors last year; authorities have opened an investigation and tightened security at the complex amid concerns for tourist safety ahead of the 2026 FIFA World Cup, which Mexico will co-host.

Satirical outlet The Onion has struck a licensing agreement to take operational control of Alex Jones’s Infowars brand and website from a court-appointed receiver, a move that must be approved by a Texas judge. Under the proposed deal filed in mid‑April 2026, The Onion’s parent, Global Tetrahedron, would pay $81,000 a month to license Infowars.com and related intellectual property for an initial six months, with an option to renew for another six. The arrangement, supported by some Sandy Hook families who won defamation judgments against Jones, is intended to convert the conspiracy-driven site into a parody and funnel any proceeds toward creditors and victims. Comedian Tim Heidecker has been named creative director as The Onion prepares prototype content. Alex Jones has publicly disputed The Onion’s claim and says he will appeal and continue broadcasting under other arrangements if removed. The licensing plan follows a voided 2024 bankruptcy sale and ongoing liquidation tied to defamation verdicts that left Jones’s operations in receivership.

U.S. Senator Mark Warner (D-Va.) and his wife, Lisa Collis, announced on April 20, 2026, that their eldest daughter, Madison Warner, has died at age 36 after a decades-long battle with juvenile (Type 1) diabetes and other health issues. The couple posted a joint statement on social media saying they are "heartbroken beyond words" and asking for privacy as they grieve. Madison, the oldest of the Warners' three daughters, is survived by her two younger sisters, Gillian and Eliza. Colleagues from both parties, including former Virginia governor Glenn Youngkin and senators across the political spectrum, offered condolences. Warner, a senior member of the Senate who has served since 2009 and is seeking a fourth term in 2026, has previously cited his family's experience with Type 1 diabetes in advocacy for diabetes research and measures to make insulin more affordable. The family did not release further details about Madison's health or the circumstances of her death.

Two teenagers were arrested after an arson attack at Kenton United Synagogue in Harrow, north‑west London, as British police probe a string of recent attacks on Jewish sites. Officers said a bottle containing an accelerant was thrown through a synagogue window around midnight on Sunday, causing minor smoke damage but no injuries. Metropolitan Police deputy commissioner Matt Jukes said the two suspects, aged 17 and 19, were taken into custody; he said the force has now made 15 arrests linked to six incidents in London over recent weeks. Counter‑terror detectives are investigating claims made online by a shadowy group calling itself Harakat Ashab al‑Yamin al‑Islamia (HAYI) and are exploring a “very serious” line of inquiry into whether the attacks were carried out by criminal “proxies” with ties to Iran. Incidents under investigation include the torching of four volunteer ambulances in Golders Green, attempted arson at other synagogues and an attack on a Persian‑language media outlet. Prime Minister Keir Starmer and senior police chiefs condemned the attacks and said visible policing and protective patrols — including drones and armed units — have been increased.
