Acting Attorney General Todd Blanche said Sunday the preliminary investigation indicated that the gunman acted alone and set out from his home in California last week before arriving in D.C. and checking into the Hilton on Friday with two firearms and a knife he had purchased years before. So far, the suspect had refused to cooperate with investigators, Blanche said. But interviews with family members as well as writings recovered from Allen’s home outside Los Angeles and the hotel room he booked at the Washington Hilton contributed to a growing confidence among authorities that his attack was politically motivated.

Caltech. Cal State Dominguez Hills. Teacher of the month. Torrance. Cole Tomas Allen, the man arrested Saturday, April 25, in the shooting at the White House correspondents’ dinner, appears to have left a trail through Southern California higher education on his alleged path to Washington, D.C. That trail, according to interviews and social media posts, shows a 31-year-old, highly educated tutor and amateur video game developer from Torrance who studied at one of the most elite learning institutions in the world, Caltech. (Carter, Emery, Saavedra and Armstrong, 4/26)

President Donald Trump lashed out at CBS News’ Norah O’Donnell in an interview Sunday for quoting from the manifesto of the suspected gunman who tried to storm the White House Correspondents Dinner less than 24 hours earlier. ... When O’Donnell, during an interview recorded at the White House on Sunday, quoted from the accused gunman Cole Allen’s apparent manifesto — “I am no longer willing to permit a pedophile, rapist, and traitor to coat my hands with his crimes,” she read — Trump, who’d been relatively subdued in his responses, flashed a familiar anger. “I was waiting for you to read that because I knew you would, because you’re horrible people. Horrible people,” Trump said. “Yeah, he did write that. I’m not a rapist. I didn’t rape anybody.” O’Donnell interjected, “Oh, do you think he was referring to you?” But the president blew past her question, declaring, “I’m not a pedophile.” (Stokols, 4/26)

When so many officials gather in one place for official functions such as an inauguration or State of the Union address, the secretary of homeland security typically puts the Secret Service in charge of coordinating all security through a formal designation known as a “National Special Security Event.” There was no such designation on Saturday night at an event also attended by thousands of journalists and other government officials, according to local and federal officials who spoke on the condition of anonymity because they were not authorized to discuss security details. ... A worst-case scenario might have resulted in passing the power of the presidency to the senior-most senator of the majority party, Chuck Grassley (R-Iowa), who was not at the event and is third in line to the presidency behind Vance and Johnson. (Davies, Arnsdorf, Roebuck and Heim, 4/26)

The gunman who sprinted through a security checkpoint on Saturday night at the Washington Hilton believed that the Secret Service was poorly prepared to guard top administration officials against him, according to writing he left behind. Agents, in turn, stopped him in a matter of seconds. The episode raised fresh questions about whether the Secret Service was sufficiently prepared to protect the president in an age of rising threats and spasms of political violence. But officials insisted that the security measures had worked as intended, pointing to the fact that the suspect never made it into the hotel ballroom where President Trump and hundreds of journalists were gathered for the White House Correspondents’ Association dinner.

A Chicago officer who was fatally shot by a man receiving treatment at a hospital while in police custody has been identified as 38-year-old John Bartholomew, authorities said. Bartholomew, a 10-year veteran of the force, was pronounced dead just before 1 p.m. Saturday after being shot at Endeavor Health Swedish Hospital, according to the Cook County Medical Examiner’s Office. A second officer was wounded in the Saturday morning shooting and remained in critical condition Sunday, police said. (4/26)

Jason Smith remembers the moment when things started to change for him, just as he was flying home to Alabama from the funeral of a former Marine colleague. It was April 2017. His friend Master Sgt. John Drascula, a decorated 24-year veteran with tours in Somalia, Afghanistan and Iraq, had died by suicide in late March. Now Smith is the director of Veterans Programs at Florida Springs Wellness and Recovery Center in Panama City, Fla., working with veterans dealing with the effects of substance abuse, post-traumatic stress and other issues. He is also a coordinator for Safer Together, a program in Alabama focused on bringing down the number of people who die by suicide using firearms, a problem that observers agree has reached unconscionable levels.

The Shreveport, La., slaying of eight children was an example of what experts call family annihilation. (Morales, 4/24)

After violent crime worsened alongside Covid-19, the federal government passed legislation including hundreds of millions of dollars in funding for community violence interventions. Community leaders and experts on crime nationwide gave some credit to these programs for helping bring homicides to historic lows in the years since. But the Trump administration withheld much of this funding upon taking office in 2025, leaving many programs scrambling to find alternative sources of support and community leaders uncertain if they can sustain the progress.

Multiple scientists who serve on an independent board established to guide the nation’s nearly $9 billion basic science funding agency were terminated from their positions Friday by President Donald Trump. Members of the National Science Board, which helps govern the National Science Foundation, were dismissed in a message from the Presidential Personnel Office thanking them for their service, according to screenshots shared with The Washington Post: “On behalf of President Donald J. Trump, I’m writing to inform you that your position as a member of the National Science Board is terminated, effective immediately.” (Johnson, 4/25)

Fewer than half of papers published by NIH-funded researchers analyze or report their data by sex, which could make it harder to know what the results mean for men and women, a new study found. (Merelli and Oza, 4/27)

For most of last year, Calley Means, a top aide to Health Secretary Robert F. Kennedy Jr., was advising on changes to the American health system while running a rapidly growing wellness company poised to benefit from Trump administration health policies. Records released to The New York Times by an ethics office at the Department of Health and Human Services show that Mr. Means held between $25 million and $50 million in stock in the company, Truemed, through November, as he continued to serve as its president. For months, Mr. Means has ignored questions from Democrats in Congress about his finances, including the extent of his stake in Truemed, and how they related to federal policy. (Jewett and Mueller, 4/24)

Leaders of Robert F. Kennedy Jr.’s Make America Healthy Again movement say they’ll help Republicans stay in power – but they’ve got little money to do it. Last month, Tony Lyons, the ally of the health secretary who runs the MAHA PAC, said he’d raise $100 million to support Republicans, bolstering President Donald Trump’s view that MAHA voters will help Republicans maintain their majorities in Congress this year.

About a quarter of people worldwide say they believe that raw milk is healthier than pasteurized milk, that use of acetaminophen during pregnancy causes autism, and that vaccines are used for population control. These are a few of the harmful health claims that were surveyed in the 5th annual Edelman Trust Barometer Special Report: Trust and Health. The report was authored by the Edelman Trust Institute. The think tank, which is part of the Edelman global communications firm, studies shifts in trust across institutions, geographies, and society. (Boden, 4/24)

Advocates for the LGBTQ+ community claimed a win this week after the Trump administration pledged to reinstate the 988 Suicide and Crisis Lifeline specialized support program tailored to their needs. During a Senate hearing earlier this week, HHS Secretary Robert F. Kennedy Jr. was asked whether he would commit to restoring the tailored line for LGBTQ+ callers to 988, as required by law, after the Trump administration removed it last summer. "We are working on getting it up now," Kennedy said. (Firth, 4/24)

The Texas Supreme Court tossed temporary injunctions Friday that halted child abuse investigations against parents who allowed their transgender kids to access puberty blockers and hormone therapy, in large part because the state has closed such inquiries into three families who sued and a fourth child is now an adult. (Langford, 4/24)

The Food and Drug Administration (FDA) announced on Friday It's issuing national priority vouchers to three companies to help fast-track the review of certain psychedelic medications. The companies are studying psilocybin for treatment-resistant depression and major depressive disorder and methylone for post-traumatic stress disorder (PTSD). These vouchers mean the FDA has 60 days to review the medications for approval. (Kekatos, 4/24)

This survey is one of the few to track psilocybin use in the previous 12 months, rather than just lifetime use. The study found that 2.8% of the U.S. population — about 8 million people — had used psilocybin during the study period. (Neff, 4/24)

Drug-making giant Johnson & Johnson will officially start marketing four of its medications on the Trump administration's TrumpRx website on Friday, CBS News exclusively learned. The pharmaceutical company announced in January that it had entered into a voluntary agreement with the Trump administration to lower costs for Americans by providing Medicaid access to affordable prescriptions and marketing its drugs on TrumpRx in exchange for exemption from the president's tariff agenda. (Rinaldi, 4/24)

Bayer AG is counting on the US Supreme Court to pare down lawsuits over its top-selling Roundup weedkiller and help corral the decade-long litigation that has cost the company more than $10 billion and cast a pall over its stock price. Bayer’s attorneys during arguments Monday will urge the high court to overturn a $1.25 million Missouri jury verdict for a man who claims Roundup caused his non-Hodgkin lymphoma and should have had a cancer warning label. The company contends that since US regulators didn’t require a cancer warning, federal law bars those types of suits. (Feeley, Stohr, and Wind, 4/26)

Scientists are making rapid progress toward a long-awaited goal that could help to reshape cancer care: mRNA cancer vaccines with the potential to significantly boost the immune system’s ability to fight and eliminate tumors. At the same time, misinformation about so-called turbo cancer began spreading widely on social media, with mainstream media outlets first reporting on it in late 2022. Turbo cancer refers to the false claim that COVID-19 mRNA vaccines cause unusually aggressive cancers. (Boatman, 4/24)

Eli Lilly & Co.’s new weight-loss pill Foundayo has gotten off to a sluggish start, according to new prescription data, an early sign of the challenge the drugmaker will have as it tries to catch up with rival Novo Nordisk A/S. Foundayo generated 3,707 prescriptions in its second week, according to IQVIA data cited by RBC Capital Markets analyst Trung Huynh. For comparison, an oral version of Novo’s Wegovy drew 18,410 prescriptions in its second week of launch. (Smith and Kresge, 4/24)

Weight-loss drugs like Ozempic could be a possible treatment for endometriosis, with research investigating the possible benefits. Although they were originally developed to treat diabetes, GLP-1 drugs like Ozempic, Mounjaro and Wegovy have been found to help with weight loss and have other benefits for the heart, kidneys and brain. Research on GLP-1s and endometriosis is in its very early stages, with few studies and more research needed. However, some women have shared experiences on social media, saying that their endometriosis symptoms improved while on a GLP-1. (Whiteside, 4/25)

The neurodegenerative disease eats away at a person’s muscles, and for Harrell, the devastation was quick and unsparing. He had already lost the ability to mount a bicycle, pick up his daughter or get out of bed on his own. Now Harrell’s voice was breaking down, making each sentence an impossible contortion.

In April 2020, people around the globe were struggling to come to grips with the strictures of unprecedented societal shutdowns aimed at slowing the spread of Covid-19. Flattening the curve, in 2020-speak. Six years later, school and business closures, mask wearing, and social distancing are dim, unpleasant memories. And Covid, though it still animates political animus plenty, feels like a threat from yesteryear. (Branswell, 4/27)

The virus that causes COVID-19 does not appear to linger in placental tissue after a pregnant patient recovers from acute infection, according to a small case-control study published this week in JAMA Network Open. The findings suggest that placental infection is unlikely in the weeks and months after illness, even in cases with adverse outcomes. (Bergeson, 4/24)

Diagnosing pneumonia in patients hospitalized for respiratory failure can be challenging, particularly when the patients are children. Children frequently carry bacterial pathogens in the upper throat and airways that could cause pneumonia. But just because those bacteria are present doesn’t necessarily mean there’s an infection, according to Emily Lydon, MD, an infectious disease (ID) physician and clinical fellow at the University of California, San Francisco (UCSF). Those pathogens might just be taking up residence. (Dall, 4/24)

Transmission of clade 1 mpox virus during commercial air travel appears to be uncommon, according to a study published yesterday in Morbidity and Mortality Weekly Report from the US Centers for Disease Control and Prevention (CDC). The analysis looked at data from five commercial flights taken by three men with active mpox symptoms to assess the risk of in-flight transmission. The three men were aged 20 to 40 years. The flights took place from November 2024 to January 2025. (Bergeson, 4/24)

Tick season seems to be off to a fast start, with an unusually high number of bites already reported across the country. Some U.S. doctors are worried about the potential for a bad year for tick-borne diseases. “If you have a lot of exposures, there will probably be more cases of tick-related infections,” said Dr. Alina Filozov, an infectious disease doctor at Middlesex Hospital in Middletown, Connecticut.

Meredith McCumbee has seen firsthand the difference applied behavioral analysis therapy, commonly known as ABA, can make in children with autism. Aaron, her 16-year-old son, was diagnosed with autism and apraxia of speech — a disorder that makes it difficult to coordinate the muscle movements needed to form words — in 2014. His inability to communicate growing up often led to aggressive “meltdowns,” his mother said, creating a near-constant state of crisis at home. (Baxley, 4/27)
